Abstract: Preparation of 2-substituted 6-methylanilines by reaction of anilines with methanol in the gas phase in the presence of supported catalysts which comprise a) vanadium pentoxide and/or chromium (III) oxide as catalyst and b) aluminium oxide and, if appropriate, copper (II) oxide and/or nickel (II) oxide as carrier, at a temperature between 250 and 550 DEG C. The 2-substituted 6-methylanilines prepared by the process are useful starting materials for the synthesis of colours, pharmaceuticals and crop protection agents.
