Versuchsvorschrift

To a solution of ethyl 2-(2-((tert-butoxycarbonyl) (2,2,2-trifluoroethyl)amino)pyridin-4-yl)-1,3-oxazole-4-carboxylate (13 g) in ethanol (100 mL) was added 2M aqueous sodium hydroxide solution (30 mL). The reaction mixture was stirred at room temperature for 16 hr, diluted with water, acidified with 1M hydrochloric acid, and extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was washed with diisopropyl ether, and dried under reduced pressure to give the title compound (10 g).
