実験手順

To a solution of 7-hydroxy-6-methoxy-4-(2-methyl-1H-indol-5-yloxy)quinazoline (225 ml, 0.7 mmol), (prepared as described in Example 49), in DMF was added powdered potassium carbonate (290 mg, 2.1 mmol) and (5S)-5-(p-toluenesulphonylmethyl)-1-methyl-2-pyrrolidinone (340 mg, 1.2 mmol). The reaction was then heated at 95° C. for 5 hours. The inorganic material was filtered off and the DMF removed by evaporation. The residue was then purified by chromatography eluting from methylene chloride to 12% methanol/88% methylene chloride (+1% ammonium hydroxide). The product was evaporated, triturated with ether and filtered to give (5S)-6-methoxy-4-(2-methyl-1H-indol-5-yloxy)-7-(1-methyl-2-oxopyrrolidin-5-ylmethoxy)quinazoline (100 mg, 33%) as a white solid.
