Procedure

To a stirred solution of 7-(1-azidoethyl)-6-(2-fluorophenyl)-3-methyl-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (0.087 g, 0.26 mmol) in tetrahydrofuran (3 mL) was added 1.00 M of trimethylphosphine in tetrahydrofuran (0.32 mL, 0.32 mmol), and the mixture was stirred at room temperature for 1 hour. The mixture was concentrated to give the crude product (0.080 g), which was used directly in next step. LCMS calculated for C15H15FN3OS (M+H)+: m/z=304.1. Found: 304.0.
