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

Participants

Reaction Steps

To a stirred solution of 7-(1-azidoethyl)-6-(3-chloro-5-fluorophenyl)-3-methyl-5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one (0.077 g, 0.21 mmol) in tetrahydrofuran (3 mL) was added 1.00 M of trimethylphosphine in tetrahydrofuran (0.25 mL, 0.25 mmol) and the mixture was stirred at room temperature for 1 hour. The mixture was concentrated to give crude product (0.070 g), which was used directly in the next step. LCMS calculated for C15H14ClFN3OS (M+H)+: m/z=338.1. Found: 338.0.
