Reaction Steps

To a solution of 7-(1-azidoethyl)-6-(2,3-difluorophenyl)-3-methyl-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (0.083 g, 0.24 mmol) in tetrahydrofuran (3 mL) was added 1.00 M of trimethylphosphine in tetrahydrofuran (0.29 mL, 0.29 mmol), and the mixture was stirred at room temperature for 1 hour. The mixture was concentrated to give the crude product (0.076 g), which was used directly in next step. LCMS calculated for C15H14F2N3OS (M+H)+: m/z=322.1. Found: 322.0.
