2-Fluorobenzyl bromide (54 uL, 0.45 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 (128 mg, 0.45 mmol) and triethylamine (76 uL, 0.54 mmol) in DMF (1 mL) at room temperature. The reaction mixture was stirred for 45 minutes, and then concentrated. Aqueous sodium bicarbonate was added, the aqueous layer extracted twice with 10% methanol/ethyl acetate, and the combined organic layers dried over magnesium sulfate, filtered, concentrated, and triturated with methanol/ether to give 9-(2-Fluorobenzyl)-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]pyrido[3,4-e] pyrimidin-5(6H)-one (Compound 13) as an off-white solid, m.p. 270°-273° C. Treatment with ethanolic HCl affords the corresponding HCl salt.
