실험 절차

0.6 g 60% NaH was added in portions to a solution of 1.23 g 2,2-difluoroethanol in 20 ml THF and stirred at room temperature for 15 minutes. 2.02 g (3-Chloro-4-fluoro-phenyl)-(7-fluoro-6-nitro-quinazoline-4-yl)-amine was added as a solid and the mixture was heated to 65° C. for 1 hour, then cooled to room temperature. Water was added and the THF was removed under vacuum. The mixture was sonicated and the resulting solids collected by filtration and dried under vacuum overnight to give 2.93 g of crude (3-Chloro-4-fluoro-phenyl)-[7-(2,2-difluoro-ethoxy)-6-nitro-quinazolin-4-yl]-amine.
