실험 절차

To a solution of 5-(2,6-dichloropyrimidin-4-yl)-3-(trifluoromethyl)pyridin-2-amine (300 mg, 0.84 mmol) in tetrahydrofuran (60 mL) was added (1S,4S)-tert-butyl 2,5-diazabicyclo[2.2.1]heptane-2-carboxylate hydrochloride (197 mg, 0.84 mmol) and N-ethyl-N-isopropylpropan-2-amine (2 mL). The mixture was heated at 75° C. for 3 h. After cooling to room temperature, water (50 mL) was added to. The mixture was extracted with ethyl acetate (3×30 mL). The organic layer was dried over sodium sulfate, concentrated and purified by flash column chromatography (25% ethyl acetate in petroleum ether to 100% ethyl acetate) to provide (1S,4S)-tert-butyl 5-(6-(6-amino-5-(trifluoromethyl)pyridin-3-yl)-2-chloropyrimidin-4-yl)-2,5-diazabicyclo[2.2.1]heptane-2-carboxylate (220 mg, 48.1% yield). TLC (Thin layer chromatography) (petroleum ether (PE): ethyl acetate (EA)=3:1, Rf=0.3-0.4).
