実験手順

To a stirred solution of 7-(1-azidoethyl)-3-methyl-6-pyridin-4-yl-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (0.050 g, 0.16 mmol) in tetrahydrofuran (0.5 mL) and water (0.12 mL) was added 1.00 M of trimethylphosphine in tetrahydrofuran (0.19 mL, 0.19 mmol) at room temperature and the mixture was stirred at room temperature for 1 hour. To the mixture was added ethyl acetate (EtOAc) and the mixture was extracted with 1 N 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, shown two peaks with same desired mass, was used directly in next step. LCMS calculated for C14H15N4OS (M+H)+: m/z=287.1. Found: 287.0.
