Procedure

4-(Isopropylamino)-6-methoxyquinazolin-7-ol (50 mg, 0.21 mmol) and (RS)-S-[3-(bromomethyl)phenyl]-N-(ethoxycarbonyl)-S-ethylsulphoximide (108 mg, 0.32 mmol) are suspended in 5.0 mL of acetone. After addition of potassium carbonate (55 mg, 0.4 mmol), the reaction mixture is refluxed for 6 hours. The batch is diluted with ethyl acetate and the organic phase is washed with water and dried over sodium sulphate to leave, after removal of the solvent and also after chromatographic purification (silica gel, hexane/ethyl acetate: 0→100% ethyl acetate, followed by ethyl acetate/methanol: 9/1) the desired product in 62% yield (65 mg).
