A process for the production of a compound of formula STR1 which comprises reacting a compound of formula STR2 or a mixture of the compounds (2a) and (2b) with a compound ZH or a compound of formula STR3 or a mixture of the compounds (2c) and (2d) with a compound YH, both reactions under acidic conditions, wherein X and Y are the same or different and each represents an aromatic carbocyclic radical having an unsubstituted or substituted amino group in the para position to the indicated bond, or a heterocyclic group, and Z represents an aryl radical of formula STR4 wherein R1 and R2 independently of one another represent hydrogen, C1 -C12 alkyl, C2 -C8 -alkoxyalkyl, cycloalkyl, aralkyl, aryl, or substituted alkyl, cycloalkyl, aralkyl or aryl, or R1 and R2 together with the nitrogen atom which links them represent a five- or six-membered, preferably saturated, heterocyclic radical and W represents hydroxy, alkoxy, aryloxy, amino or substituted amino, and the aromatic carbocyclic radical of formula (1a) or (1b) may be further substituted by one or more halogen, cyano, nitro, alkyl of 1 to 4 carbon atoms or alkoxy of 1 to 4 carbon atoms, V represents oxygen, sulphur or imino and T1 and T2 independently represent hydrogen, C1 -C12 -alkyl, C2 -C12 -alkenyl, aryl, aralkyl, and T1 also amido or ureido, or T1 and T2 together with the nitrogen atom which links them represent a five- or six-membered heterocyclic radical.
