Participants

Reaction Steps

To a stirred solution of {(1R, 2R)-2-[4-(6-Trifluoromethyl-benzo[b]thiophen-3-yl)-piperazin-1-ylmethyl]-cyclopropyl}-methanol (3.712 g, 10.03 mmol) in Et3N (8.5 mL, 61.1 mmol) and anhydrous CH2Cl2 (100 mL ) at 0° C. under N2 was added dropwise CH3SO2Cl (930 uL, 12.02 mmol ). Stirring was continued at 0° C. for 2.5 h. The reaction was quenched with H2O (20 mL). A solution of K2CO3 (4.28 g, 31.01 mmol) in H2O (60 mL) was then added. The resulting mixture was stirred at rt for 15 min, then extracted with CH2Cl2, washed with brine, dried over Na2SO4. Filtration, concentration and drying afforded the desired product (4.301 g, 96%).
