実験手順
Add palladium over carbon 10% (0.6 g) to a suspension of 4-(6-nitro-pyridin-3-yloxy)-piperidine-1-carboxylic acid tert-butyl ester (5.65 g) in a mixture tetrahydrofuran (THF)/methanol (30/30 mL/mL). Hydrogenate in a Parr apparatus at 2 atm overnight. Filter through a celite pad, wash with DCM and methanol. Purify by silica gel column chromatography eluting with DCM/methanol (10%)/ammonia (1%) to afford 5 g of the title compound. MS (ES+): m/z=294 (M+H)+.
