実験手順

A mixture of 4-chloro-2-fluoro-3-hydroxyaniline (118 mg, 0.7 mmol), (EP 061741 A2), and 4-chloro-6-methoxy-7-((4-pyridyl)methoxy)quinazoline (200 mg, 0.7 mmol), (prepared as described for the starting material in Example 13), in isopropanol (10 ml) and ethereal hydrogen chloride (5 ml) was heated at 80° C. for 2 hours and the mixture was allowed to cool. The precipitated product was collected by filtration, washed with isopropanol and dried to give 4-(4-chloro-2-fluoro-5-hydroxyanilino)-6-methoxy-7-((4-pyridyl)methoxy)quinazoline hydrochloride (110 mg, 31%).
