실험 절차

To a stirred solution of 7-(1-azidoethyl)-3-methyl-6-(1,3-thiazol-2-yl)-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (0.030 g, 0.094 mmol) in tetrahydrofuran (0.3 mL) and water (0.068 mL) was added 1.00 M of trimethylphosphine in tetrahydrofuran (0.11 mL, 0.11 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 1N HCl two times. The combined extracts were neutralized with solid sodium bicarbonate, and extracted with dichloromethane. The combined organic layers were washed with brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was used directly in next step. LCMS calculated for C12H13N4OS2 (M+H)+: m/z=293.1. Found: 293.0.
