Participants

Reaction Steps

To a solution of N2′-(trans-4-aminocyclohexyl)-5′-chloro-5-fluoro-N6-((4-methyltetrahydro-2H-pyran-4-yl)methyl)-2,4′-bipyridine-2′,6-diamine (21 mg, 0.048 mmol) in DCM (1.0 ml) was added 2-methyl-1,3-dioxolane-2-carbaldehyde (synthesized following the procedure reported in Org. Lett., 2009, 11, 3542-3545), sodium triacetoxyborohydride (20.51 mg, 0.097 mmol). The reaction mixture was stirred at ambient temperature for 2 hours. The reaction mixture was diluted with water and extracted with ethyl acetate. The combined extracts were washed sequentially with water and brine, dried over sodium sulfate, filtered, and concentrated. The residue was purified by reverse phase HPLC and lyophilized to give 12 mg off-white powder of the title compound as its TFA salt. LCMS (m/z): 534.1 (MH+), retention time=0.62 min.
