Participants

Reaction Steps

Propionyl chloride (39 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 (2 mL) at room temperature. The reaction mixture was stirred for 50 minutes, and then poured into ice water. The precipitate was collected, washed with water and 95% ethanol, and dried to yield 9-propionyl-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]pyrido[3,4-e] pyrimidin-5(6H)-one (Compound 36) as a white solid, m.p. >310° C.
