Abstract

Procedure for the preparation of amides derived from 4-aminopipexidine, of the general formula **(See formula)** where R is a methoxy or ethoxy group; R1 is a hydrogen atom or an amino group; R2 is a halogen atom, a sulfonamido or alkylsulfonyl group; R3 is a hydrogen atom or a lower alkyl group of 1-4 carbon atoms; R4 and R5 are interchangeably hydrogen, lower alkyl of 1-4 carbon atoms, methoxy, halogen, nitro or R4 and R5 together form a methylenedioxy group. W is a single bond or an alkylene or alkenylene group; characterized in that a general structure (II) salicylamide is reacted: **(See formula)** (R1, R2, R3, R4, R5 and W being what has been previously defined) with a sulfate or lower alkyl halide (methyl or ethyl), the reaction being carried out in a solvent such as acetone, tetrabidrofuran or dioxane at a temperature between 10 and 80 & 0, preferably using salicylamide II in the form of an alkali metal salt or in the presence of an inorganic base, and once the reaction is complete, the product is isolated by precipitation over water or by removal of the solvent.
