Procedure: To a solution of oxalyl chloride (0.45 mL, 5.2 mmol) in dry dichloromethane (15 mL) at −78° C. is added a solution of DMSO (0.73 mL, 10.3 mmol) in dichloromethane (10 mL) dropwise, and the resulting mixture is allowed to stir at −78° C. for 30 minutes. Then a solution of 2-(4-Fluoro-phenyl)-cyclohexanol (500 mg, 2.57 mmol) in dichloromethane (5 mL) is added and stirred for 15 minutes. Then triethylamine (2.87 mL, 15.4 mmol) is added and the reaction is allowed to slowly warm up to 20° C. and stirred for 16 hours. The mixture is poured into ice-water (30 mL) and organic layer is washed with water (10 mL×5), then brine (10 mL×1) and dried over anhdrous sodium sulfate. After concentration, the crude is purified by silica flash column chromatography using EtOAc in Heptane (gradient from 0% to 30%) to give 342 mg of the desired product. stirred for 15 minutes to slowly warm up to 20° C. stirred for 16 hours is washed with water (10 mL×5) brine (10 mL×1) and dried over anhdrous sodium sulfate After concentration the crude is purified by silica flash column chromatography
