Reaction Steps

To a solution of 504.9 mg (1.20 mmol) of 4-(6-amino-7-ethylamino-4-quinazolinyl)-N-benzyl-1-piperazinethiocarboxamide obtained in Example 461 in 15 ml of dichloromethane were added 0.50 ml (3.6 mmol) of triethylamine and 0.17 ml (1.44 mmol) of benzoyl chloride, followed by overnight stirring at room temperature in an atmosphere of argon. After addition of water, the reaction mixture was extracted with dichloromethane, and the organic layer was washed with water and dried over sodium sulfate. After the solvent was evaporated, the residue was purified by silica gel chromatography to give the desired compound as colorless crystals.
