실험 절차

To a mixture of rac-N-[(1R,2R,4S)-bicyclo[2.2.1]hept-2-yl]-5-(chloromethyl)-4-(trifluoromethyl)pyrimidin-2-amine (200 mg) and N,N-dimethyl formamide (3 mL) was added morpholine (0.57 mL), and the mixture was stirred at room temperature for 15 hours. The solvent was evaporated under reduced pressure from the reaction mixture, and water was added to the residue, 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. The residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate). The obtained colorless oil was dissolved in 1,4-dioxane (5 mL), and a 4 M hydrogen chloride/1,4-dioxane solution (1 mL) was added thereto, followed by stirring at room temperature for 1 hour. The precipitated solid was collected by filtration and washed with 1,4-dioxane to obtain rac-N-[(1R,2R,4S)-bicyclo[2.2.1]hept-2-yl]-5-(morpholin-4-ylmethyl)-4-(trifluoromethyl)pyrimidin-2-amine hydrochloride (187 mg) as a white solid.
