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) (40 mg, 0.09 mmol), methylamine hydrochloride (7 mg, 0.11 mmol), WSC hydrochloride (59 mg, 0.31 mmol), HOBT (21 mg, 0.15 mmol), diisopropylethylamine (0.020 mL, 0.11 mmol), dichloromethane (0.75 mL) and DMA (0.75 mL), to obtain 30 mg of the title compound as a white solid (73%).
