実験手順

A suspension of 4-chloro-6-methoxy-7-(1-methylpiperidin-4-ylmethoxy)quinazoline (200 mg, 0.62 mmol) and 4-bromo-2-fluoroaniline (142 mg, 0.74 mmol) in isopropanol (3 ml) containing 6N hydrogen chloride in isopropanol (110 μl, 0.68 ml) was heated at reflux for 1.5 hours. After cooling, the precipitate was collected by filtration, washed with isopropanol followed by ether and dried under vacuum to give 4-(4-bromo-2-fluoroanilino)-6-methoxy-7-(1-methylpiperidin-4-ylmethoxy)quinazoline hydrochloride (304 mg, 90%).
