Procedure

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. LCMS (m/z): 562.3 (MH+), retention time=0.70 min; 1H NMR (400 MHz, DMSO-d6) δ ppm 1.01-1.33 (m, 4H) 1.35-1.65 (m, 4H) 1.64-1.84 (m, 1H) 1.93-2.23 (m, 4H) 2.94-3.18 (m, 4H) 3.17-3.35 (m, 3H) 3.53-3.69 (m, 1H) 3.81 (dd, J=11.35, 2.74 Hz, 2H) 4.33-4.48 (m, 1H) 6.38 (s, 1H) 6.55 (d, 1H) 6.82 (br. s., 1H) 6.93 (br. s., 1H) 7.23 (br. s., 1H) 7.48 (d, 1H) 8.02 (s, 1H) 8.72 (br. s., 2H)
