Reaction Steps

To a solution of tert-butyl [(3S,5R)-5-methyl-1-(5-nitro-2,3-dihydrofuro[2,3-b]pyridin-4-yl)piperidin-3-yl]carbamate (44.5 mg, 0.118 mmol) in MeOH (2.00 mL), 10 wt % Pd on carbon (9.3 mg, 0.0087 mmol) was added under a nitrogen atmosphere. The mixture was then hydrogenated (1 atm.) for 4 h. The reaction mixture was then filtered through a pad of diatomaceous earth (eluted with MeOH). The filtrate was concentrated under reduced pressure to give the crude product as a red semi-solid (41.0 mg). The crude product was used directly in the next step without further purification. LCMS calc. for C18H29N4O3 (M+H)+: m/z=349.2. found 349.2.
