PROCEDURE
实验过程
A suspension of 4-chloro-6-methoxy-7-(1-(2-methylsulphonylethyl)piperidin-4-ylmethoxy)quinazoline (115 mg, 0.28 mol) and 3-(4-methoxyphenyl)-4,5-dihydro-1H-pyrazol-5-one (65 mg, 0.33 mol), (prepared as described for the starting material in Example 10), in DMF (1.5 ml) containing potassium carbonate (60 mg, 0.42 mol) was heated at 100° C. for 30 minutes. After cooling, water was added. The precipitate was collected by filtration, washed with water and dried under vacuum. The solid was dissolved in methylene chloride/methanol and pentane was added. The precipitate was collected by filtration, washed with pentane and dried under vacuum to give 4-(5-(4-methoxyphenyl)pyrazol-3-yloxy)-6-methoxy-7-(1-(2-methylsulphonylethyl)piperidin-4-ylmethoxy)quinazoline (120 mg, 75%).
