Reaction Steps
A 0° C. solution of 4-chloro-3-nitrobenzenesulfonyl chloride (12.8 g, 50.0 mmol) in diethyl ether (1 L) was slowly treated with 0° C. concentrated NH4OH (50 mL) and stirred for 30 minutes. The organic layer was dried (MgSO4), filtered, and concentrated to provide the desired product of sufficient purity for subsequent use.
