Reaction Steps

1-(4-bromophenyl)piperazine (1 g, 4.15 mmol) was dissolved in DCM (40 ml) and cooled in 0° C. Then DMAP (0.051 g, 0.415 mmol), triethylamine (0.723 ml, 5.18 mmol), and cyclopropanesulfonyl chloride (0.641 g, 4.56 mmol) were added. The reaction was stirred 1 h at rt, then diluted with DCM and saturated NH4Cl/water (1:1). The aqueous phase was separated, extracted with DCM (×2) and the combined extracts were washed with brine, dried over Na2SO4, filtered and concentrated to give the desired product. LC-MS: calculated for C13H17BrN2O2S 346.02 observed m/e: 346.88 (M+H)+ (Rt 1.16/2 min).
