4-Chloro-2-fluoroaniline → 7-Benzyloxy-4-(4-chloro-2-fluorophenylamino)-6-methoxyquinazoline hydrochloride

Participants

Reaction Steps

A solution of 7-benzyloxy-4-chloro-6-methoxyquinazoline hydrochloride (1.34 g, 4 mmol), (prepared as described for the starting material in Example 1), and 4-chloro-2-fluoroaniline (444 μl, 4 mmol) in isopropanol (40 ml) was refluxed for 1.5 hours. After cooling, the precipitate was collected by filtration, washed with isopropanol then ether and dried under vacuum to give 7-benzyloxy-4-(4-chloro-2-fluoroanilino)-6-methoxyquinazoline hydrochloride (1.13 g, 64%).
