Procedure

The same operation as in Example (106d) was performed using butyl cis(±)-2-(4-amino-3-methoxypiperidin-1-yl)-5-ethyl-1,3-oxazole-4-carboxylate obtained in Example (110c) (0.35 g, 1.45 mmol), 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid (0.11 g, 0.6 mmol), WSC hydrochloride (0.38 g, 2 mmol), HOBt (0.13 g, 1 mmol), DMA (3 mL) and dichloromethane (3 mL). The resulting residue was purified by silica gel column chromatography (elution solvent: ethyl acetate/hexane=1/4, 1/2, 3/2, 2/1) to obtain 0.23 g of the title compound as a colorless solid (80%).
