The present invention relates to a novel 1-phenyl-2,5-benzoxazosine derivative and its production method. Administration of morphine analgesics is unavoidable in order to alleviate severe pain such as cancer pain, but its high narcotic properties make it unsuitable for long-term administration or intensive administration even for short periods of time. . This is because it has the potential to cause poisoning and even lead to incompetence. On the other hand, even among drugs that have traditionally been considered non-narcotic analgesics, some with strong effects have been found to have narcotic properties. We can't help but think that there is some kind of correlation. For this reason, there is currently a strong desire for analgesics that are non-narcotic, have a wide safety margin, and have mild effects. Therefore, an object of the present invention is to provide a compound that can be used as an active ingredient of this type of analgesic drug with mild action, and a method for producing the same. Compounds according to the invention have the formula (In the formula, R is a phenethyl group, or a hydroxy group, a halogen atom, a nitro group, an amino group, a group -NHCOCH=CHCOOC 2 H 5 , -NHCOCH 2 Br,
-NHCOCH2CH2COOC2H5 or a substituted phenethyl group having a 3,4-dehydro-succinimide group, or a p-fluorobenzoylpropyl group), a novel 1 - phenyl- It is a 2,5-benzoxazosine derivative or a pharmacologically acceptable salt thereof. The compound represented by the formula and its salt is a new substance that has not been described in any literature, and according to the method of the present invention, the compound represented by the formula Starting from 1-phenyl-1,3,5,6-tetrahydro-5H-benz[f]-2,5-oxazosine shown in (In the formula, X means a halogen atom, R 1 is hydrogen,

IRスペクトルνKBr naxcm-1:2250〜2700[Formula] or b) Formula A free base is obtained by reacting with a compound represented by the formula (wherein X has the above-mentioned meaning), and a salt thereof can be obtained by treating the base in a conventional manner. The compound of the formula used as a starting material can be synthesized starting from 2-benzoylbenzoic acid as shown in the reaction formula below [see Japanese Patent Publication No. 44-8512 and "Bull.Soc.
Chim” Vol. 10, p. 347 (1943)]. Next, the present invention will be explained in more detail with reference to production examples and pharmacological test examples. Production Example 1 1-Phenyl-5-(p-hydroxyphenethyl-1,3,4,6-tetrahydro-5H-benz[f]-2,5oxazosine 1-phenyl-1,3,4,5- 24.5 g (58.5 mmol) of tetrahydro-5H-benz[f]-2,5-oxazocine oxalate as the free base was dissolved in 500 ml of dry CHCl 3 and triethylamine 8
g (79.2 mmol) and p
-Acetoxyphenylacetyl chloride 14g
(70.52 mmol) in 100 ml of CHCl 3 was added dropwise over 40 minutes, then after stirring at room temperature (rising to 15°C in 20 minutes), the solvent was distilled off, 150 ml of tetrahydrofuran and 150 ml of ethyl ether were added, and ice 12 g of LiAlH 4 was added under cold stirring, refluxed for 5 minutes, then decomposed with water, extracted with CH 2 Cl 2 and further extracted with ethyl acetate, the extracts were combined, dried and the solvent was evaporated. Then, the target compound is obtained by dissolving it in a 1:1 mixture of CH 2 Cl 2 and ethyl acetate and purifying it by silica gel column chromatography. When the target compound is converted into its hydrochloride and recrystallized from methanol, 14.5 g (62.8%) of colorless needles are obtained.

-Tetrahydro-1-phenyl-5H-benz[f]-2,5-oxazosine Add 3.5 g of 1-phenyl-1,3,5,6-tetrahydro-5H-benz[f]-2,5-oxazosine oxalate. To the free base were added 40 ml of dry dimethylformamide, 1.2 g of NaHCO 3 and 3 g of p-nitrophenethyl bromide, and the mixture was stirred at 100-105° C. for 6 hours under nitrogen atmosphere. After cooling, the reaction mixture was poured into ice water and extracted with ether. The ether extract was washed with water, dried over Na 2 SO 4 and filtered, and the ether was distilled off from the liquid. The obtained oil was purified by silica gel column chromatography (ether), then converted to hydrochloride, dissolved in 80 ml of methanol, and added with 5%
Catalytic reduction treatment was performed by adding 0.4 g of Pd-C. After stirring for about 2 hours, remove the catalyst by filtration,
Methanol was distilled off from the liquid. Aqueous ammonia and ether were added to the obtained residue for extraction treatment, and the ether layer was separated, washed with water, dried over Na 2 SO 4 and the ether was distilled off to obtain an oily substance. The target compound is obtained by purifying this oil by silica gel column chromatography (ether). This was further converted into hydrochloride, dissolved in methanol,
Then, an ether solution of hydrochloric acid was added to completely convert the dihydrochloride. Adding methyl ethyl ketone while distilling off methanol yields 2.3 g (63.9 g) of hydrochloride.

To a solution of 1.00 g (2.79 mmol) of tetrahydro-5H-benz[f]-2,5-oxazosine in 20 ml of tetrahydrofuran was added 328 mg (3.35 mmol) of maleic anhydride under an argon atmosphere, and the mixture was refluxed for 1.5 hours. After cooling, 30 ml of ethyl ether was added and 1.24 g (97.5%) of the resulting crystals were collected. Add 28 ml of Ac 2 O to this crystal under a stream of argon.
560 mg (6.83 mmol) of NaOAc was added and the mixture was refluxed for 2 hours. The reaction mixture was concentrated under reduced pressure, neutralized with NaHCO3 solution, extracted with CH2Cl2 , washed with water , dried over Na2SO4 , further concentrated under reduced pressure, and subjected to column chromatography (20 g of silica gel, ethyl ether). Separation and purification was performed to obtain 1.00 g (81.8%) of a compound with Rf = 0.2 (silica gel, ethyl ether). If this is added to a solution of fumaric acid in methyl ethyl ketone and crystallized, a fumarate salt can be obtained.

Nefopam, a known analgesic, was selected as a control substance and the analgesic effect, acute toxicity and edematability were tested. The results are shown in the table below, and from this it can be seen that the compound according to the present invention is a non-narcotic analgesic. Compared to Nefopam, which is said to be a drug, its effects are almost the same and the safety margin is broader, so it can be seen that it satisfies the current requirements as an analgesic.
