Reaction Steps

A solution of 4-chloro-3-nitro-benzene sulfonamide (5.49 g, 23.2 mmol), cyclohexylamine (4.00 mL, 35.0 mmol), and triethylamine (5.0 mL, 35 mmol) in acetonitrile (75 mL) was refluxed overnight under nitrogen atmosphere. The reaction mixture was concentrated almost to dryness. The residue was diluted in ethyl acetate and washed with 1N hydrochloric acid (1×) and saturated NaHCO3 (1×). The organic layer was dried (MgSO4) and concentrated on a rotary evaporator. The residue was filtered and washed with hexane to give the product as a yellow solid (6.34 g, 91%). ESI-MS m/e 300.1 (M+1).
