Reaction Steps

To a 100-mL round-bottomed flask was added 2-(3-methoxybenzyl)piperazine (128 mg, 0.62 mmol), 5 mL of CH2Cl2, triethylamine (0.129 mL, 0.93 mmol) and 2-thiophenesulfonyl chloride (0.113 mL, 0.62 mmol, Aldrich, St. Louis, Mo.). The reaction mixture was stirred at 0° C. for 1 h and then diluted with aqueous saturated NaHCO3 (5 mL) and extracted with EtOAc (2×30 mL). The organic extracts were washed with saturated NaCl (10 mL) and dried over Na2SO4. The solution was filtered and concentrated in vacuo to give the crude material as a light-yellow oil. The crude product was purified by silica gel chromatography, eluting with 5% MeOH in EtOAc to give 3-(3-methoxybenzyl)-1-(thiophen-2-ylsulfonyl)piperazine as a colorless oil (162 mg).
