Versuchsvorschrift

A solution containing 44 g (0.32 m) of 3-aminobenzamide, 71.6 g (0.32 m) of p-nitrobenzenesulfonyl chloride and 700 ml of pyridine was stirred and heated on a steam bath for 2.5 hours, then poured into ice water. Acetic acid was added to a pH 5.0-6.0 and the resulting solid collected by filtration, washed with water and air-dried to give 105 g, m.p. 240°-244°.
