Reaction Steps

Trifluoroacetic acid (5 eq) was added to a solution of tert-butyl 4-(5-nitropyridin-2-yloxy)piperidine-1-carboxylate (1 eq) in dichloromethane, stirring at room temperature for 1 hour. The solvent was then evaporated, the residue brought to pH=10 with sat. aq. Na2CO3 solution and extracted with EtOAc. The organic layer was washed with brine, dried over sodium sulfate and evaporated to afford the product as a light yellow crystalline solid. LC/MS (m/z): 224.3 (MH+), Rt 1.64 minutes
