Hydrobromic acid/acetic acid solution (1 mL) was added to ethyl trans(±)-2-(3-{[(benzyloxy)carbonyl]amino}-4-{[(4-chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}piperidin-1-yl)-4-methyl-1,3-thiazole-5-carboxylate obtained by the method described in Example (79e) (62 mg, 0.11 mmol), and the mixture was stirred for 25 minutes. Saturated aqueous sodium bicarbonate solution was added to the reaction solution. Purification by reverse phase silica gel chromatography (elution solvent: distilled water, distilled water/THF=70/30, 60/40) gave 51.3 mg of the title compound (100%).
