Derivatives of 2-aminobenzenesulphonic acid and of 2-aminobenzenesulphonyl chloride, their preparation and their use as synthetic intermediates
摘要：
The present invention provides a compound of formula (1) ##STR1## in which: R.sub.4 represents a hydrogen atom, a halogen atom or a nitro group; R.sub.6 represents a hydrogen atom or a straight or branched (C.sub.1 -C.sub.6) alkyl group; R.sub.7 represents a chlorine atom or a hydroxyl group; and Z represents: a phenyl group optionally substituted with one or more halogen atoms, straight or branched (C.sub.1 -C.sub.4)alkyl groups, straight or branched (C.sub.1 -C.sub.4)alkoxy groups, or trifluoromethyl, formyl, --CH.sub.2 OR, --CH.sub.2 OCOR, --CH.sub.2 CONRR', --CH.sub.2 ONCOR, --COOR, nitro, --NHR, --NRR' or --NHCOR groups, wherein R and R' are each, independently, a hydrogen atom or a (C.sub.1 -C.sub.7) alkyl group; a heterocyclic group optionally substituted as defined above for phenyl; or a cyclo(C.sub.5 -C.sub.8)alkyl group; additionally, when R.sub.7 represents chlorine, Z can represent iodine; in the free form or in the form of a salt with an alkali metal or tertiary amine, processes for their preparation and their use as synthetic intermediates.
