Hexane → 4-(4-Chloro-2,6-difluoroanilino)-6,7-dimethoxyquinazoline hydrochloride

Participants

Reaction Steps

4-Chloro-6,7-dimethoxyquinazoline hydrochloride (210 mg, 0.8 mmol), (prepared as described for the starting material in Example 1 but without the aqueous work up), and 4-chloro-2,6-difluoroaniline hydrochloride (177 mg, 0.89 mmol) in isopropanol (8 ml) were heated at reflux for 2 hours. The reaction mixture was then allowed to cool, hexane added and the precipitated product collected by filtration, washed with isopropanol and dried to give 4-(4-chloro-2,6-difluoroanilino)-6,7-dimethoxyquinazoline hydrochloride (45 mg, 16%).
