NOVEL PROCESS FOR THE PREPARATION OF 2-AMINOMETHYLPYRIDINE DERIVATIVES

摘要

The present invention relates to a novel process for the preparation of 2-amino-methylpyridine derivatives of the formula (I), comprising reacting in a first step 2-substituted pyridine derivatives of the formula (II), with a nitroalkane of the formula (III), in the presence of a base resulting in 2-nitromethylpyridine derivatives of the formula (IV) and hydrogenating these 2-nitromethylpyridine derivatives of the formula (IV) in a second step in the presence of a catalyst and in the presence of an acid, where in the formulae n, X, Y, R<1>, R<2> and A are as defined in the description.
