Reaction Steps

A mixture of 4-(3'-chloro-4'-fluoroanilino)-6-hydroxy-7-methoxyquinazoline (1.28 g), 3-(pyrrolidin-1-yl)propyl chloride hydrochloride (Chem. Abs., 82, 57736; 1.5 g), potassium carbonate (2.8 g) and DMF (20 ml) was stirred and heated to 80° C. for 5 hours. The mixture was cooled to ambient temperature and partitioned between ethyl acetate and water. The organic phase was washed with water, dried (MgSO4) and evaporated. The residue was purified by column chromatography using a 20:3 mixture of methylene chloride and methanol as eluent. The material so obtained (1.1 g) was triturated under ethyl acetate to give 4-(3'-chloro-4'-fluoroanilino)-7-methoxy-6-(3-pyrrolidin-1-ylpropoxy)quinazoline (0.094 g). The organic solution was evaporated and the residual solid was recrystallised from acetonitrile. There was thus obtained a second crop (0.85 g) of the same product. The material gave the following characterising data:
