Abstract
Procedure for obtaining azo compounds of difficult solubility in water, of formula: ** (See formula) ** where R1 is chosen from hydrogen, chlorine, bromine, nitro, cyano and acyl, R2 is chosen from hydrogen, chlorine, bromine and cyano, R3 is phenyl, which can have substituents, R4 is chosen from hydrogen, acylamino and alkyl, which may bear substituents, is chosen from a group of the formula -NH2, -NH-alkyl, -N (alkyl) 2, -NH-alkylene-R6, -N (alkylene-R7) 2 and (see formula), one chooses from chlorine, bromine, hydroxy, acyl, acyloxy and alkoxy, which can have substituents, phenoxy, alkoxycarbonyl, phenoxycarbonyl, alkoxycarbonyloxy, alkylaminocarbonyl, phenylaminocarbonyl, alkylaminocarbonyloxy and phenylaminocarbonyloxy, one of which is R7 from the meanings of R6 and cyano and R8 is chosen from one of the meanings of R6, cyano and hydrogen, the molecule being, however free of sulfonic radicals, characterized in that an amine of formula: ** (See formula) ** it is diazotized and the obtained diazoic compound is coupled with a compound of formula: (see formula) (Machine-translation by Google Translate, not legally binding)
