4-Chloro-3-nitro-benzenesulphonyl chloride (2.56 g, 10 mmol) was added in small portions to a solution of N-methyl piperazine (1.33 ml, 12 mmol) in DCM (25 ml) at 0° C. To this solution was added triethylamine (2.08 ml, 15 mmol) dropwise. The reaction mixture was stirred at ambient temperature for 2 h and then reduced in vacuo. The residue was partitioned between ethyl acetate and water, and the organic layer washed with brine, dried (MgSO4) and reduced in vacuo. Purification with column chromatography eluting with 0-20% methanol in ethyl acetate gave 1-(4-chloro-3-nitro-benzenesulphonyl)-4-methyl-piperazine as an off-white solid (1.84 g, 58%). (LC/MS: Rt 1.84, [M+H]+ 319.97).
