Procedure

1,1-Dimethylethyl 4-[(5-cyclopropyl-3-fluoro-2-nitrophenyl)amino]-1-piperidinecarboxylate (D26, 0.8 mmol, 300 mg) was dissolved in MeOH (15 ml) and it was reduced by THALIS H-CUBE apparatus (bought from Asynt) using a palladium cartridge. The process yielded 280 mgs of the title compound, complete conversion, M+−COOC(CH3)3=250.
