Versuchsvorschrift

To a mixture of methyl 2-chloro-4-(trifluoromethyl)pyrimidine-5-carboxylate (4.0 g), rac-(1R,2R,4S)-bicyclo[2.2.1]heptan-2-amine (3.7 g), and 1,4-dioxane (60 mL) was added N,N-diisopropyl ethylamine (4.3 mL) at room temperature, and the mixture was stirred at the same temperature for 19 hours. To the reaction mixture were added water and 1 M hydrochloric acid, followed by extraction with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over anhydrous magnesium sulfate, and then the solvent was evaporated under reduced pressure to obtain methyl rac-2-[(1R,2R,4S)-bicyclo[2.2.1]hept-2-ylamino]-4-(trifluoromethyl)pyrimidine-5-carboxylate (5.2 g) as a yellowish white solid.
