Reaction Steps
A suspension of 4-chloro-6-methoxyquinazolin-7-ol (0.6 g, 2.86 mmol), 1 bromo 4 chlorobutane (0.63 g, 3.7 mmol), potassium carbonate (1.19 g, 8.6 mmol) and dimethylformamide (10 ml) were heated to 95 C for 1.5 hours. The excess potassium carbonate was filtered off and the reaction evaporated under reduced pressure. The residue was purified by flash chromatography on silica eluting with a mixture of 60-100% dichloromethane in hexane and 30-50% ethyl acetate in hexane to give 4-chloro-7-(4-chlorobutoxy)-6-methoxyquinazoline as a solid (0.4 g, 47%)
