To a solution of 6-methyl-N,N-di-BOC-3′-nitro-4,4′-bipyridin-2-amine in EtOH/EtOAc (1:1, 0.2M) was added Pd/C (10% by weight) and the reaction was stirred under a H2 balloon for 18 hrs. Filtered through Celite, washed with EtOAc and concentrated the filtrate to afford 6-ethyl-N2,N2-di-BOC-4,4′-bipyridine-2,3′-diamine in >95% yield. LCMS (m/z): 401.0 (MH+); LC Rt=2.81 min.
