Reaction Steps

1-(4-Nitrophenyl)piperazine (2.79 g, 13.5 mmol) was dissolved in dichloromethane (100 ml). Triethylamine (2.25 ml, 16.2 mmol) was added and the reaction was cooled to 0° C. Methanesulfonyl chloride (1.15 ml, 14.9 mmol) was added dropwise and the reaction was stirred at 0° C. for 1 h. Saturated sodium bicarbonate was added and the reaction was extracted (×3) with dichloromethane, dried (MgSO4), filtered and concentrated in vacuo to give 4-(4-nitrophenyl)-1-methylsulfonylpiperazine as a yellow solid (3.83 g, quantitative yield). GC/MS (EI, M+) m/z=285.
