Procedure

To a solution of 528 mg (1.25 mmol) of 4-(6-amino-7-ethylamino-4-quinazolinyl)-N-benzyl-1-piperazinethiocarboxamide obtained in Example 461 in 15 ml of dimethylformamide were added 0.57 ml (4.09 mmol) of triethylamine and 0.31 ml (1.55 mmol) of methanesulfonyl chloride, followed by overnight stirring at room temperature in an atmosphere of argon. To the resulting mixture was added 0.06 ml (0.31 mmol) of methanesulfonyl chloride, followed by overnight stirring at room temperature. The reaction mixture was poured into water, and sodium chloride was added thereto. The precipitated crystals were collected by filtration, washed with water, and dried, followed by purification by silica gel chromatography to give the desired compound as colorless crystals.
