PROCESS FOR THE PREPARATION OF 2-METHOXYMETHYL-1,4-BENZENEDIAMINE, ITS DERIVATIVES THEREOF AND THE SALTS THEREOF

摘要

A process for synthesizing 2-methoxymethyl-1,4-benzenediamine, its derivatives of formula (IV) and the salts thereof, which comprises a reductive amination step. The preferred final product is 2-methoxymethyl-1,4-benzenediamine of formula (IV-a). (Formulae IV, IV-a). These compounds may be used as primary intermediates in compositions for dyeing keratin fibers.
