Reaction Steps

To a 100-mL round-bottomed flask was added 2-((2-methoxy-4-pyridinyl)methyl)piperazine (350 mg, 1.69 mmol), triethylamine (0.353 mL, 2.54 mmol), and 2-thiophenesulfonyl chloride (0.34 mL, 1.86 mmol, Aldrich, St. Louis, Mo.) in DCM (5 mL). The reaction mixture was stirred at 0° C. for 30 min. The reaction mixture was diluted with saturated NaHCO3 (10 mL) and extracted with EtOAc (2×40 mL). The organic extract was washed with saturated NaCl (5 mL) and dried over Na2SO4. The solution was filtered and concentrated in vacuo to give the crude material as light-yellow oil. The crude product was purified by silica gel chromatography, eluting with 10% MeOH/EtOAc to give 3-((2-methoxy-4-pyridinyl)methyl)-1-(2-thiophenylsulfonyl)piperazine (198 mg) as colorless glass.
