Reaction Steps

A mixture of 4-chloro-3-nitroaniline (5.0 g, 29 mmol), methanesulfonyl chloride (2.37 mL, 30.4 mmol) and pyridine (5.9 mL, 72.4 mmol) in THF (100 mL) was stirred for 24 h. Poured in 1M HCl (500 mL). The resulting precipitate was filtered and air-dried to provide the title compound as a solid (6.7 g, 92%).
