Trimethylphosphine → 7-(1-aminoethyl)-6-(5-fluoropyridin-3-yl)-3-methyl-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one

Participants

Reaction Steps

To a solution of 7-(1-azidoethyl)-6-(5-fluoropyridin-3-yl)-3-methyl-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (0.020 g, 0.060 mmol) in tetrahydrofuran (3 mL) was added 1.00 M of trimethylphosphine in tetrahydrofuran (0.079 mL, 0.079 mmol), and the mixture was stirred at room temperature for 1 hour. The mixture was concentrated to give the crude product (0.018 g), which was used directly in next step. LCMS calculated for C14H14FN4OS (M+H)+: m/z=305.1. Found: 305.0.
