Reaction Steps

To a scintillation vial containing N2′-(trans-4-aminocyclohexyl)-5′-chloro-N6-(3-fluorobenzyl)-2,4′-bipyridine-2′,6-diamine (17 mg, 0.040 mmol) and K2CO3 (22.06 mg, 0.160 mmol) was added DMF (0.3 ml) and (2-bromoethoxy)(tert-butyl)dimethylsilane (9.55 mg, 0.040 mmol). The reaction mixture was capped and heated to 75° C. for 7 hr. The reaction mixture was diluted with DCM and washed with H2O, sat NaCl. The organic layer was dried over Na2SO4, filtered and concentrated. The crude solid was purified by reverse phase preparative HPLC. Collected fractions were combined, neutralized with Saturated NaHCO3 and extracted with EtOAc. The organic layer was dried over Na2SO4, filtered, concentrated and used directly in next step. LCMS (m/z): 584.3 (MH+), retention time=0.87 min.
