Definitions
- the present invention relates to a novel process for producing lacosamide. More specifically, the present invention relates to a method for producing lacosamide in a high chiral purity and environmentally friendly method through a simple process.
- Lacosamide is first reported in US 5773475 as an amino acid derivative with analgesic and anticonvulsant activity. According to this document, lacosamide reacts intermediates, which are N-acetyl derivatives prepared by reacting D-serine with acetic anhydride, again with benzylamine to produce benzylamide derivatives. The benzyl amide derivative is then O-methylated with silver oxide (I) and methyl iodide to produce lacosamide.
- this method is very unsuitable for mass production and difficult to use industrially because it has a very low yield and causes partial racemization in the O-methylation process and uses expensive silver oxide (I).
- D-serine is N-protected with a tert- butoxycarbonyl (Boc) group and O-methylated.
- the compound thus obtained is reacted with benzylamine to produce an amide compound and undergoes N-deprotection of the Boc group followed by acetylation to produce lacosamide.
- benzylamine since the reaction uses an organic solvent and water that are not well mixed during the O-methylation process, a phase transfer catalyst must be used and an expensive organic lithium compound must be used for efficient reaction progression.
- the Boc group undergoes N-protection and N-deprotection, there is a disadvantage in that the process becomes longer.
- the method of manufacturing lacosamide developed so far uses a protecting group that is steric hindrance to the amine of D-serine in order to minimize the occurrence of racemization in the O-methylation process, and the process is carried out to deprotect it again.
- Samamide is prepared.
- the present invention provides a method for preparing a lacosamide compound represented by Chemical Formula 1 by reacting a compound represented by Chemical Formula 2 with a methylating agent in the presence of an inorganic lithium compound to prepare a compound represented by Chemical Formula 3.
- Bn represents a benzyl group.
- Lacosamide production method of the present invention is easy to mass production because it can be produced in a simple process with high chiral purity using a environmentally friendly solvent without the use of a phase transfer catalyst or other expensive materials and shows a high yield Can be applied.
- the compound represented by Chemical Formula 3 may be prepared using only water as a solvent.
- the compound represented by Chemical Formula 3 may be prepared by adding the inorganic lithium compound to an aqueous solution containing the compound represented by Chemical Formula 2 and then adding a methylating agent.
- the addition of the inorganic lithium compound may be to add an aqueous solution containing an inorganic lithium compound.
- the present invention does not need to use a phase transfer catalyst or the like because no organic solvent other than water is used as a solvent when preparing the compound of Formula 3, and the reaction may be performed in an environment-friendly atmosphere.
- the methylating agent is dimethyl sulfate.
- the methylating agent may be added by dividing the methylating agent three times.
- the compound represented by Chemical Formula 2 may be prepared by reacting D-serine with acetic anhydride.
- the reaction of the D serine and acetic anhydride may be used as a solvent a mixture of water and C1-C3 alcohol, preferably a mixture of water and methanol as a solvent.
- reaction of D-serine with acetic anhydride (Ac 2 O) may be carried out in the presence of sodium bicarbonate (NaHCO 3 ), potassium bicarbonate (KHCO 3 ) or a mixture thereof.
- NaHCO 3 sodium bicarbonate
- KHCO 3 potassium bicarbonate
- the inorganic lithium compound may be lithium hydroxide (LiOH) or a hydrate thereof, which serves as a base, and preferably lithium hydroxide monohydrate.
- the compound represented by Chemical Formula 3 in the presence of isobutylchloroformate (IBC) and a base may be reacted with benzyl amine (BnNH 2 ) to prepare lacosamide represented by Chemical Formula 1.
- the base may be a tertiary amine, preferably 4-methylmorpholine (NMM), triethylamine, pyridine or a mixture thereof, and more preferably methylmorpholine.
- NMM 4-methylmorpholine
- pyridine pyridine or a mixture thereof, and more preferably methylmorpholine.
- isobutylchloroformate and a base are added to the compound represented by Chemical Formula 3 to prepare a mixture, and benzyl amine is added to the mixture to prepare a reaction mixture.
- the indicated lacosamide can be prepared.
- the preparation of the mixture and the reaction solution may be performed at -20 ° C to -5 ° C, and preferably at -15 ° C to -10 ° C.
- the step of stirring the reaction solution may be performed at room temperature.
- the lacosaamide may be prepared by a method represented by the following scheme.
- the present invention can perform O-methylation of D serine in high chiral purity without the use of toxic organic solvents or catalysts, thereby providing an environmentally friendly and economical method for producing lacosamide.
- HPLC HPLC was measured using Agilent Technoliges 1200Series and 1H NMR was Oxford NMR 300MHz from Varian Mercury Instrument (Varian Mercury) Measurement was made using a spectrometer. Purity and chiral purity were determined by area% of HPLC.
- (R) -2-acetamido-3-hydroxypropanoic acid (compound represented by Chemical Formula 2) (7 g, 0.0476 mole) was dissolved in 60 ml of purified water, cooled to 0-10 ° C., maintained at 20 wt% Lithium hydroxide monohydrate (10 g, 0.238 mole) aqueous solution was added dropwise and stirred for 20 minutes. Dimethyl sulfate (13.6ml, 0.1428mole) at the same temperature was added dropwise three times at 30 minute intervals and stirred at the same temperature for 3 hours, and then heated to room temperature (20-25 ° C.).
- the mixture was maintained at -15 ° C to -10 ° C for 1 hour, heated to room temperature, and stirred for 3 hours.
- the reaction solvent was removed by concentration, 130 ml of methylene chloride and 13 ml of purified water were added and extracted.
- the aqueous layer was reextracted with 60 ml of methylene chloride, and the oil layers were combined.
- the separated oil layer was washed with 100 ml of 2 wt% aqueous hydrochloric acid solution, 100 ml of 2 wt% aqueous sodium bicarbonate solution and 10 wt% brine, and then separated into oil layers, and the separated oil layer was concentrated under reduced pressure.
- the present invention can perform O-methylation of D serine with high chiral purity without the use of toxic organic solvents or catalysts, and thus can be usefully provided by providing an eco-friendly and economical method for producing lacosamide.
