실험 절차

A mixture of 2-(2-Fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazolin-5(6H)-one (283 mg) and 50% sodium hydride (144 mg) in DMF (5 mL) was stirred at room temperature for 15 min. Acetyl chloride (1 mL) was added and stirring was continued for 30 min. The reaction was diluted with ethyl acetate and washed with water. After drying over magnesium sulfate, the solvent was removed in vacuo and he residue was subjected to flash chromatography on silica gel with 30% ethyl acetate in hexane as the eluent to afford 6-Acetyl-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazolin-5(6H)-one (Compound 47) and 5-Acetoxy-2-(2-fluorophenyl)-7,8,9,10-tetrahydro-imidazo[1,2-c]-quinazoline (Compound 48) as white solids.
