To a solution of 7-hydroxy-4-(1H-indol-5-yloxy)-6-methoxyquinazoline (800 mg, 2.6 mmol), (prepared as described for the starting material in Example 107), in DMF (20 ml) was added powdered potassuim carbonate (1.08 g, 7.8 mmol) and (5R)-5-(p-toluenesulphonylmethyl)-2-pyrrolidinone (1.13 g, 4.2 mmol). The reaction was then heated at 90° 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). A small portion was recolumned using the same gradient. The product was evaporated, triturated with ether and filtered to give (5R)-4-(1H-indol-5-yloxy)-6-methoxy-7-(2-oxopyrrolidin-5-ylmethoxy)quinazoline (70 mg, 6.5%) as a white solid.
