Procedure

To a solution of 1.01 g (2.15 mmol) of N-(4-bromophenyl)-4-(6,7-dimethoxy-4-quinazolinyl)-1-piperazinecarboxamide obtained in Example 45 in 15 ml of dimethylformamide was added 171.9 mg (4.30 mmol) of 60% sodium hydride under ice-cooling, followed by stirring at room temperature for 30 minutes. To the reaction mixture was added 0.27 ml (4.34 mmol) of methyl iodide, followed by overnight stirring at room temperature. The resulting 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 column chromatography to give the desired compound as colorless crystals.
