Procedure
4N Hydrogen chloride-ethyl acetate (1 ml) was added to tert-butyl 3-[4-[[(4′-chloro[1,1′-biphenyl]-4-yl)carbonyl]amino]benzoyl]-1-piperidinecarboxylate (100 mg, 0.193 mmol) obtained in 1). One hour later, the solvent was distilled out under reduced pressure. Diisopropyl ether was added to the residue, to give the titled compound (73.3 mg) as a colorless powder.
