Procedure

2-Chloro-5-(chlorosulfonyl)nicotinic acid (400 mg, 1.56 mmol) was stirred in a slurry of ice and excess ammonium hydroxide was added at 0° C. and stirred until all of the ice had melted. The resulting solution was evaporated to afford a white solid 5-(aminosulfonyl)-2-chloronicotinic acid. MS ES+ 237 (M+H). 1H NMR (400 MHz, DMSO-D6) δ ppm 8.1 (dd, J=2.6, 0.9 Hz, 1H), 8.6 (m, 1H).
