Vorschrift

To a mixture of 4-{[2-chloro-4-(trifluoromethyl)pyrimidin-5-yl]carbonyl}thiomorpholin-1,1-dioxide (100 mg), 3-exo-hydroxymethylbicyclo[2.2.1]heptyl-2-exo-amine hydrochloride (129 mg), and 1,4-dioxane (3 mL) was added N,N-diisopropyl ethylamine (0.20 mL) at room temperature, and the mixture was stirred at 80° C. for 2 hours. To the reaction mixture was added water and the aqueous layer was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate, and then the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate) to obtain rac-[(1R,2S,3R,4S)-3-({5-[(1,1-dioxidothiomorpholin-4-yl)carbonyl]-4-(trifluoromethyl)pyrimidin-2-yl}amino)bicyclo[2.2.1]hept-2-yl]methanol (72 mg) as a white solid.
