Procedure

The same operation as in Example (1g) was performed using tert-butyl cis(±)-4-amino-3-methoxypiperidine-1-carboxylate obtained by the method described in Example (1e) (0.20 g, 0.87 mmol), 5-ethyl-1H-imidazole-2-carboxylic acid obtained in Example (lb) (85 mg, 0.44 mmol), WSC hydrochloride (0.55 g, 2.87 mmol) and DMAP (115 mg, 0.94 mmol), to obtain 85 mg of the title compound as a pale yellow solid (55%).
