Reaction Steps

To a solution of 502.7 mg (1.19 mmol) of 4-(6-amino-7-ethylamino-4-quinazolinyl)-N-benzyl-1-piperazinethiocarboxamide obtained in Example 461 in 10 ml of ethanol were added 1.66 ml (11.9 mmol) of triethylamine and 10 ml (166 mmol) of carbon disulfide, followed by overnight stirring at room temperature in an atmosphere of argon. After the solvent was evaporated, the residue was purified by silica gel chromatography to give the desired compound as colorless crystals.
