실험 절차

To a stirred solution of 7-(1-azidoethyl)-6-(3-fluorophenyl)-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (0.32 g, 1.0 mmol) in tetrahydrofuran (5 mL) and water (1 mL) was added 1.00 M of trimethylphosphine in tetrahydrofuran (1.22 mL, 1.22 mmol) at room temperature, and the mixture was stirred at room temperature for 1 hour. To the mixture was added ethyl acetate, and the mixture was extracted with aqueous 1 N HCl solution (three times). The combined extract was neutralized with solid NaHCO3 and extracted with dichloromethane (two times). The combined organic layer was washed with brine, dried over Na2SO4, and concentrated to give the desired product (0.17 g, 58%). LCMS calculated for C14H13FN3OS (M+H)+: m/z=290.1. Found: 290.0.
