Procedure

The same operation as in Example (1g) was performed using tert-butyl cis(±)-4-amino-3-propoxypiperidine-1-carboxylate obtained by the method described in Example (113d) (125.5 mg, 0.49 mmol), 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid obtained by the method described in Example (1d) (74 mg, 0.42 mmol), WSC hydrochloride (235 mg, 1.23 mmol) and HOBT (56 mg, 0.41 mmol), to obtain 145.6 mg of the title compound as a white foamy substance (83%).
