Participants

Reaction Steps

Benzyl chloroformate (57 uL, 0.4 mmol) was added to a solution of 2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]pyrido[3,4-e] pyrimidin-5(6H)-one (124 mg, 0.4 mmol) and triethylamine (74 uL, 0.5 mmol) in DMF (1 mL) at room temperature. The reaction mixture was stirred for 1 hour, then poured into ice water. The precipitate was collected, washed with 95% ethanol and ether, and subsequently dried to give 9-Carbobenzyloxy-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]pyrido[3,4-e] pyrimidin-5(6H)-one (Compound 44). Recrystallization from aqueous ethanol afforded Compound 41 as an off-white solid, m.p. 250° C. (d).
