Reaction Steps

To a parr flask was added 6′-Amino-5′-nitro-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-ol (10.0 g, 42.0 mmol) (Step 1), 10% Pd/C (2.5 g) and MeOH (100 mL). The flask was pressurized to 50 psi with H2 for 12 hr with shaking. The contents of the flask were filtered through Celite and the filtrate (dark green) was concentrated to afford 5′,6′-Diamino-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-ol as a dark purple solid (8.90 g, 39.7 mmol, 95%). MS ESI m/z 209.2 (M+H)+.
