4-Bromo-2-fluoroaniline → 7-Benzyloxy4-(4-bromo-2-fluoroanilino)-6-methoxyquinazoline hydrochloride

Participants

Reaction Steps

A solution of 7-benzyloxy-4-chloro-6-methoxyquinazoline (8.35 g, 27.8 mmol), (prepared as described for the starting material in Example 1), and 4-bromo-2-fluoroaniline (5.65 g, 29.7 mmol) in 2-propanol (200 ml) was heated at reflux for 4 hours. The resulting precipitate was collected by filtration, washed with 2-propanol and then ether and dried under vacuum to give 7-benzyloxy-4-(4-bromo-2-fluoroanilino)-6-methoxyquinazoline hydrochloride (9.46 g, 78%).
