Reaction Steps

Sodium hydride (400 mg of an 80% suspension in paraffin oil, 13.3 mmol) was added to a solution of phenol (1.26 g, 13.3 mmol) in dry 1-methyl-2-pyrrolidinone (20 ml) and the mixture stirred for 10 minutes. 7-Benzyloxy-4-chloro-6-methoxyquinazoline (1.6 g, 5.3 mmol), was then added and the reaction mixture heated at 110° C. for 2 hours. The mixture was allowed to cool, water was added and the mixture extracted with ethyl acetate (3×100 ml). The combined extracts were then washed with 2M sodium hydroxide solution, water and brine. Removal of the solvent under reduced pressure gave 7-benzyloxy-6-methoxy4-phenoxyquinazoline (1.6 g, 84%) as a yellowish solid.
