Procedure

The same operation as in Example (196c) was performed using tert-butyl cis(±)-4-{[(4-chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}-3-(isopropylamino)piperidine-1-carboxylate obtained in Example (211a) (24.0 mg, 0.058 mmol), 4 N hydrochloric acid/1,4-dioxane (2 mL), ethyl 2-bromo-1,3-benzothiazole-7-carboxylate obtained in Example (1f) (18 mg, 0.064 mmol) and sodium carbonate (61 mg, 0.580 mmol), to obtain 10 mg of the title compound (33%) as a colorless solid.
