Procedure

The same operation as in Example (1g) was performed using tert-butyl trans(±)-4-amino-3-{[(benzyloxy)carbonyl]amino}piperidine-1-carboxylate obtained in Example (79c) (98 mg, 0.28 mmol), 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid obtained by the method described in Example (1d) (48 mg, 0.25 mmol), WSC hydrochloride (150 mg, 0.78 mmol) and HOBT (35 mg, 0.26 mmol), to obtain 88.2 mg of the title compound as a white solid (69%).
