Abstract

Amino-diphenyl derivatives of the general formula <FORM:0597809/IV/1> where X is chlorine or -NH2 and A is an amino group or a group convertible into an amino group by hydrolysis or reduction are made by a process which comprises the treatment of a compound of the formula <FORM:0597809/IV/2> where B is a group convertible into an amino group by reduction or hydrolysis with chlorsulphonic acid, treatment of the sulphonyl chloride so formed with ammonia and finally hydrolysis or reduction to form the amino group. To prepare the starting materials: (a) diphenyl is nitrated with a mixture of nitric and sulphuric acids and the required 2-nitrobiphenyl is separated; (b) the 2-nitrobiphenyl prepared as above is reduced with hydrochloric acid and iron filings; (c) the aminobiphenyl produced in (b) is acetylated by treatment with acetic anhydride. In examples, (1) the 2-acetylaminobiphenyl prepared above is treated with chlorsulphonic acid to produce p - (o - acetamidophenyl) benzenesulphonyl chloride; (2) the compound produced in concentrated ammonia; (3) the amination product of example (2) above is hydrolyzed to give p-(o-aminophenylbenzenesulphonamide; (4) 2-nitrobiphenyl produced as above is treated with chlorsulphonic acid; (5) p-(o-nitrophenyl)benzenesulphonyl chloride is aminated with concentrated ammonium hydroxide to p - (o - nitrophenyl) - benzenesulphonamide. (6) the compound produced in example (5) is reduced with tin and hydrochloric acid to form the same compound as was formed in example (3) above.
