Procedure
The same operation as in Example (106d) was performed using butyl cis(±)-2-(4-amino-3-ethoxypiperidin-1-yl)-5-methyl-1,3-oxazole-4-carboxylate obtained in Example (112h) (0.66 g, 2.03 mmol), 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid (85% content, 0.2 g, 1 mmol), WSC hydrochloride (0.5 g, 2.5 mmol), HOBt (0.2 g, 1.5 mmol), dichloromethane (5 mL) and DMA (3 mL), to obtain 0.21 g of the title compound as a yellow amorphous solid (44%).
