Reaction Steps
A solution of 7-benzyloxy-4-chloro-6-methoxyquinazoline hydrochloride (1.2 g, 4 mmol), (prepared as described in WO 97/22596, Example 1), and 4-chloro-2-fluoroaniline (444 μl, 4 mmol) in 2-propanol (40 ml) was heated at reflux for 1.5 hours. After cooling, the precipitate was collected by filtration, washed with 2-propanol then ether and dried under vacuum to give 7-benzyloxy-4-(4-chloro-2-fluoroanilino)-6-methoxyquinazoline hydrochloride (1.13 g, 64%).
