To a solution of N2′-(trans-4-aminocyclohexyl)-3,5′-dichloro-N6-((tetrahydro-2H-pyran-4-yl)methyl)-2,4′-bipyridine-2′,6-diamine (54 mg, 0.120 mmol) in 2-propanol (0.4 mL) was added (S)-(−)-3,3,3-trifluoro-1,2-epoxypropane (10.4 uL, 0.120 mmol). The mixture was stirred at 70° C. for 2 hr. The reaction mixture was concentrated. The resulting residue was purified by reverse phase HPLC and lyophilized to give 32 mg of (S)-3-(trans-4-(3,5′-dichloro-6-((tetrahydro-2H-pyran-4-yl)methyl)amino-2,4′-bipyridin-2′-yl-amino)cyclohexylamino)-1,1,1-trifluoropropan-2-ol as its TFA salt.
