Procedure

7-Benzyloxy-4-chloro-6-methoxyquinazoline hydrochloride (3.35 g) was dissolved in methylene chloride (250 ml) and washed with aqueous sodium hydrogen carbonate until the pH of the aqueous solution was adjusted to pH8. The organic layer was washed with brine, dried (MgSO4) and evaporated to give 7-benzyloxy-4-chloro-6-methoxyquinazoline free base (2.9 g, 96%).
