反応手順
A mixture of 4-chloro-8-fluoroquinazoline (1.82 g, 0.01 mol), 2-(4-(5-trifluoromethyl-2-pyridinyloxy)-phenyl)ethylamine (2.82 g, 0.01 mol), triethylamine (1.1 g, 0.011 mol) and ethanol (50 mL) was heated under reflux for three hours and allowed to cool. Solvent was evaporated under reduced pressure, and the residue dissolved in dichloromethane. This was washed with 0.5M sodium hydroxide solution and water, and dried over anhydrous sodium sulphate. Evaporation of the solvent under reduced pressure and recrystallization from ethyl acetate:hexane gave 2.5 g of product. MP 152° C.
