Reaction Steps

To a solution of 7-hydroxy-4-(1H-indol-5-yloxy)-6-methoxyquinazoline (600 mg, 1.95 mmol), (prepared as described for the starting material in Example 107), in DMF (20 ml) was added powdered potassuim carbonate (540 mg, 3.9 mmol) and (5S)-5-(p-toluene-sulphonylmethyl)-2-pyrrolidinone (580 mg, 2.16 mmol). The reaction was then heated at 100° C. for 4 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)-4-(1H-indol-5-yloxy)-6-methoxy-7-(2-oxopyrrolidin-5-ylmethoxy)quinazoline (240 mg, 31%) as a white solid.
