Reaction Steps

Chlorobenzene (0.4 ml) was added to the compound (3) (205 mg) and 4-chloro-6,7-dimethoxyquinazoline (252 mg), and the mixture was stirred at 140° C. overnight. A saturated aqueous sodium hydrogencarbonate solution was added to the reaction solution, and the mixture was extracted with chloroform, followed by washing with saturated brine. The extract was then dried over anhydrous sodium sulfate. The solvent was removed by distillation under the reduced pressure. The residue was purified by chromatography on silica gel using hexane/acetone for development to give the title compound (128 mg, yield 37%).
