Process for the preparation of alkyl ethers of morphine.
EMI1.1
108075, by treating the morphine in an alkaline solution with the neutral esters of inorganic acids. The neutral esters of organic acids, especially the esters of aromatic sulfonic acids, are also used to esterify other organic substances
EMI1.2
to introduce radical into a carboxyl group. (See English patent 16067/1899.
Conversion of the dialkylrhodamines into their ethyl esters). However, recent studies have shown that these sulfonic acid esters are also very suitable for replacing the hydrogen of the phenolic hydroxide in morphine with alcohol radicals, if only in
EMI1.3
with additional patents. If an alcoholic solution of sodium morphine benzenesulfonic acid methyl ester is allowed to act, codeine is already formed at ordinary temperature. The reaction can also be hastened by gentle warming, so that the formation of ether is completed in the shortest possible time. The ethyl ether of morphine is produced in exactly the same way when using ethyl benzenesulfonate; on the other hand, other sulfonic acid esters, z.
B. α- or β-naphthalenesulphonic acid esters, toluene or chlorosulphonic acid esters and the like, and instead of morphine sodium the corresponding morphine compounds of the other alkali metals and alkaline earth metals can be used.
Example:
100 parts of sodium morphine are dissolved in 900 parts of methyl alcohol, and 60 parts of methyl benzenesulfonate are added to the solution. One puts the mixture some

formation of escaped morphine isolated in a known manner.
