実験手順

A 100 ml stainless steel autoclave was charged with about 50 ml of liquid ammonia. Then 4-chloro-3-nitrobenzenesulfonamide (5.0 g, 21 mmol) was added and the bomb was heated in an oil bath at 100° C. for 3 h. Excess ammonia was allowed to evaporate, and the solid residue was successively washed with water, cold ethanol and ether to give 3.9 g (85%) of the title compound. M.p. 211.5°-213° C. (ethanol); 1H-NMR (DMSO-d6): 6.97 (d,J=9Hz, 1H, H-5), 7.12 (s, 2H, NH2), 7.57 (dd, J6-5 =9 Hz, J6-2 2Hz, H-6), 7.70 (broad s, 2H, NH2), 8.22 (d,J 2Hz, H-2).
