実験手順

To a solution of (±)-2-[1-(2-amino-2-methyl-propylamino)-2-methyl-propyl]-3-benzyl-7-chloro-3H-quinazolin-4-one (133 mg, 0.32 mmol) in dichloromethane (3 mL) was added triethylamine (90 μL, 0.64 mmol), followed by 3-fluoro-4-methylbenzoyl chloride (51 μL, 0.35 mmol). The resultant solution was stirred at ambient temperature for 3 hours, quenched with saturated aqueous sodium bicarbonate (5 mL) and diluted with dichloromethane (5 mL). The aqueous layer was extracted with dichloromethane (5 mL) and the combined extracts were dried over magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography (10–20% ethyl acetate/hexanes) to give (±)-N-{2-[1-(3-benzyl-7-chloro-4-oxo-3,4-dihydro-quinazolin-2-yl)-2-methyl-propylamino]-1,1-dimethyl-ethyl }-3-fluoro-4-methyl-benzamide (120 mg, 68%) as a white solid.
