실험 절차

A mixture of Intermediate B (preparation of intermediate B is described in the intermediate session which is in front of the Examples) (25 mg, 0.075 mmol), tert-butyl (1S,2S,4S)-4-amino-2-methylcyclohexylcarbamate/tert-butyl (1R,2R,4R)-4-amino-2-methylcyclohexylcarbamate (25.8 mg, 0.113 mmol), triethylamine (28 μl, 0.201 mmol) in DMSO (0.25 mL) was heated at 100° C. for 3 days. The mixture was allowed to cool to ambient temperature and diluted with EtOAc (20 mL) and saturated aqueous NaHCO3 solution (10 mL). The separated aqueous layer was extracted with EtOAc (3×). The combined organic layers were dried over Na2SO4, filtered off and concentrated in vacuo providing crude tert-butyl (1S,2S,4S)-4-(5′-chloro-6-(3-fluorobenzylamino)-2,4′-bipyridin-2′-yl-amino)-2-methylcyclohexylcarbamate/tert-butyl (1R,2R,4R)-4-(5′-chloro-6-(3-fluorobenzylamino)-2,4′-bipyridin-2′-yl-amino)-2-methylcyclohexylcarbamate, which was directly used in the next step without further purification.
