Abstract
Improvements introduced in the object of the main patent No. 399,875, applied for on February 17, 1972, for: "Procedure for the preparation of N- (furyl-methyl) -morphonanes" of the general formula **(See formula)** wherein R signifies a hydrogen atom or a methyl or acetyl group and R1 signifies a hydrogen atom or a methyl or ethyl group, and of their acid addition salts, characterized in that a morphinan of the formula is reacted **(See formula)** wherein R'means a hydrogen atom, an alcohol, aralcohyl or acyl group, with a quaternary ammonium salt of the formula **(See formula)** wherein Z signifies a hydrogen atom, a methyl or ethyl group, or a substituent that can be transformed by chemical reaction into a hydrogen atom or a methyl or ethyl group, and A signifies the anion of an organic or inorganic acid, to form a compound of the formula **(See formula)** in which R'and Z have the meanings mentioned above; and if compounds of formula IV are obtained, in which Z does not have the meaning of R1-the substituent Z is transformed by chemical reaction into a hydrogen atom or a methyl or ethyl group; and if desired - for the preparation of a compound of the formula I, in which R signifies a hydrogen atom, a compound of the formula is dealkoxylated or deacylated **(See formula)** where R1 has the meanings mentioned above and R'means an alcoholic, aralcohyl or acyl group; and if desired - for the preparation of a compound of the formula I, in which R means a methyl or acetyl group - a compound of the formula IVa is methylated or acetylated, in which R1 has the aforementioned meanings and R' designates a hydrogen atom, and eventually the compounds of the general formula I are transformed into their physiologically harmless acid addition salts.
