A mixture of 4-[{N-(2-(tert-butoxycarbonylamino)-4,5-difluorobenzoyl)glycyl}aminomethyl]-1-(4-chloro-3-nitrobenzyl)piperidine (121 mg, 0.20 mmol), 10% palladium-activated carbon (85 mg), ethyl acetate (10 mL), and methanol (1 mL) was stirred under a hydrogen atmosphere at room temperature for 19 h. The Pd catalyst was filtered off and the filtrate was concentrated to afford 1-(3-amino-4-chlorobenzyl)-4-[{N-(2-(tert-butoxycarbonylamino)-4,5-difluorobenzoyl)glycyl}aminomethyl]piperidine (78 mg, 68%).
