実験手順
To a scintillation vial containing 5′-chloro-2′-fluoro-6-(3-fluorobenzylamino)-2,4′-bipyridine-4-carbonitrile (72 mg, 0.202 mmol) was added DMSO (3 ml) and trans-cyclohexane-1,4-diamine (230 mg, 2.018 mmol). The homogenous yellow reaction mixture was capped and heated to 105° C. in a oil bath for 3 hr. The reaction mixture was diluted with EtOAc and washed with sat NaHCO3, sat NaCl. The organic layer was dried Na2SO4, filtered and concentrated. The crude solid was purified by Prep HPLC and the collected fractions were combined and diluted with EtOAc and neutralized with sat NaHCO3 and then sat NaCl. The organic layer was dried over Na2SO4, filtered and concentrated to afford 2′-(trans-4-aminocyclohexylamino)-5′-chloro-6-(3-fluorobenzylamino)-2,4′-bipyridine-4-carbonitrile (73 mg, 80%).
