실험 절차

A suspension of 4-chloro-6-methoxy-7-(1-methylpiperidin-4-ylmethoxy)quinazoline (200 mg, 0.622 mmol), (prepared as described for the starting material in Example 2c) and 2-fluoro-4-methylaniline (94 mg, 0.764 mmol) in isopropanol (5 ml) containing 6.2M hydrogen chloride in isopropanol (110 μl) was stirred at 80° C. for 1.5 hours. After cooling, the precipitate was collected by filtration, washed with isopropanol, followed by ether and dried under vacuum. The solid was purified by column chromatography, eluting with methylene chloride/methanol (90/10) followed by 5% ammonia in methanol/methylene chloride (10/90). Evaporation of the fractions containing the expected product gave 4-(2-fluoro-4-methylanilino)-6-methoxy-7-(1-methylpiperidin-4-ylmethoxy)quinazoline (170 mg, 61%).
