실험 절차

A solution of Example 176 (69.3 mg, 0.135 mmol) and 1,1′-thiocarbonyldiimidazole (38.1 mg, 0.203 mmol) in anhydrous tetrahydrofuran (1.3 mL) was stirred under nitrogen at 25° C. for 1.5 hours. Ethyl acetate (25 mL) was added, the mixture was washed with H2O (2×10 mL) and brine (10 mL), dried over anhydrous MgSO4, filtered, and concentrated by rotary evaporation to provide the title compound as a yellow foam (84 mg, 0.135 mmol, 100%).
