実験手順

To a stirred solution of 7-(1-azidoethyl)-3-methyl-6-phenyl-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (0.044 g, 0.14 mmol) in tetrahydrofuran (0.4 mL) and water (0.102 mL) was added 1.0 M of trimethylphosphine in tetrahydrofuran (0.17 mL) at room temperature and the mixture was stirred at room temperature for 1 hour. To the mixture was added EtOAc and the mixture was extracted twice with 1 N HCl. The combined extracts were neutralized with solid sodium bicarbonate and extracted with methylene chloride. 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 (36 mg, 89.3%). LCMS calculated for C15H16N3OS (M+H)+: m/z=286.1. Found: 286.0.
