Abstract

Title cpds. of formula (I): (where R1 is H, Cl, Br, 1-4C alkyl or alkoxy, or NHCO(1-4 C)alkyl; R2 is H or SO3M in posn. 5 or 7; X is - R3 is H, OCH3 or OC2H5; R4 is H, 1-4C alkyl, C2H4-SO3M or (1-4C)alkylene-OR5; R5 is H, cyclohexyl, (1-4C)alkylcyclohexyl, benzyl, (tetrahydro)furfuryl, 1-6C alkylene- R6 or R7; R6 is H, CN, OH, 1-4C alkoxy or OR7; R7 is phenyl opt. substd. by one or two Cl, Br, NO2, CF3, 1-4C alkyl and/or 1-4C alkoxy; R8 is H or SO3M; M is H, Li, Na, K, NH4 or di- or tri-(hydroxy-2-3C alkyl)-ammonium; providing that only one SO3M gp. is present), are prepd. by diazotising an R1- and R2-substd. 3-aminobenzisothiazole and coupling it with gamma-acid (7-amino-1-naphthol-3-sulphonic acid) or with an amine contg. the substnts. R3,R4 and R8.
