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) (300 mg, 1.30 mmol), 4,5-dibromoimidazole-2-carboxylic acid obtained in Example (2a) (300 mg, 1.11 mmol), WSC hydrochloride (460 mg, 2.40 mmol) and DMAP (50 mg, 0.41 mmol), to obtain 384 mg of the title compound as a white solid (72%).
