1,145,385. Reactive azo dyes. SANDOZ Ltd. 8 July, 1966 [16 July, 1965], No. 30825/66. Heading C4P. The invention comprises compounds of the formula where R is a heterocyclic reactive group which bears at least one mobile chlorine or bromine atom and which may be bound through CO, CH 2 or SO2; X is hydrogen, halogen, alkyl of 1-5 carbon atoms or alkoxy of 1-5 carbon atoms and Y is hydrogen, methyl or alkoxy of 1-5 carbon atoms. The compounds are prepared by reacting 1 mol. of an amine of the formula with 1 mol. of a heterocyclic reactive component which may bear a halomethyl, halocarbonyl or halosulphonyl group, or with 1 mol. of an acylating agent, followed by diazotization and coupling with a compound of the formula followed, if necessary, by cleavage of the acyl group and reaction with 1 mol. of a heterocyclic reactive component which may bear a halomethyl, halocarbonyl or halosulphonyl group.
