Reaction Steps

The same operation as in Example (1g) was performed using cis(±)-2-(4-{[(4-chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}-3-methoxypiperidin-1-yl)-4-methyl-1,3-thiazole-5-carboxylic acid obtained in Example (14a) (30 mg, 0.07 mmol), tert-butyl 4-aminopiperidine-1-carboxylate (16 mg, 0.08 mmol), WSC hydrochloride (44 mg, 0.23 mmol), HOBT (16 mg, 0.12 mmol), diisopropylethylamine (0.015 mL, 0.08 mmol), dichloromethane (0.75 mL) and DMA (0.75 mL), to obtain 31 mg of the title compound as a white solid (87%).
