Procedure

To a −78° C. mixture of cyclopropylamine (10 g, 1.75 mmol) in CH2Cl2 (100 mL) was added a solution of 2-nitrobenzene sulfonyl chloride (22.1 g, 85.7 mmol) and the mixture was stirred for 12 h. The mixture was washed with 1N HCl dried over MgSO4 then concentrated to give 18.7 g, (88%) of a N-Cyclopropyl-2-nitro-benzenesulfonamide as a tan solid.
