실험 절차
To a stirred solution of DMSO (5.84 mL, 82.2 mmol) in dry DCM (220 mL) was added (COCl)2 (3.55 mL, 41.1 mmol) at −78° C. and the mixture stirred at same temperature for 20 minutes. A solution of compound 49 (6 g, 27.4 mmol) in DCM (30 mL) was then added slowly and the reaction mixture was stirred at −78° C. for 1 hour. TEA (13.8 mL, 137 mmol) was added at −78° C. and the reaction mixture was stirred and allowed to come to rt. The reaction mixture was diluted with DCM and the organic layer was washed with water and brine, dried over anhydrous Na2SO4, filtered and concentrated to provide sticky compound 50.
