Abstract

559,775. Para-aminobenzene-sulphonamidonaphthalene compounds. BUTLER, G. C., LOZINSKI, E., and ODELL, A. D. Feb. 11, 1942, No. 1806. [Class 2 (iii)] Para - aminobenzene - sulphonamido naphthalene compounds are prepared by the action of a para acylamino substituted benzene sulphonyl halide on a 4-amino-1-naphthol containing an organic substituent in position - 2 followed by hydrolysis of the acylamino group. In examples (1) 2-Allyl-4-amino-1- naphthol is reacted in dioxane solution with p-acetamino-benzene sulphonyl chloride and the condensation product hydrolysed to give N-(p-aminobenzenesulphonyl)-2-allyl - 4 -amino- 1-naphthol. (2) 1-Hydroxy-4-amino-2-naphthoic acid is reacted in dioxane solution with pacetamino benzene sulphonyl chloride and the reaction product hydrolysed to give N-(paminobenzenesulphonyl)-1-hydroxy-4-amino-2- naphthoic acid.
