Zusammenfassung:A telescoping process for the preparation of 2-methoxymethyl-p-phenylenediamine, a cosmetically acceptable salt thereof, or mixture thereof. The process according to the present invention is a particularly cost effective process in that it avoids sophisticated chemical steps which requires special equipment or expensive catalysts and in that it comprises a recycling step of one of the starting materials, namely 2-hydroxymethylaniline.
