실험 절차

The same operation as in Example (106d) was performed using tert-butyl cis(±)-4-amino-3-propoxypiperidine-1-carboxylate obtained in Example (113d) (0.73 g, 2.8 mmol), 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid (85% content, 0.61 g, 2.98 mmol), WSC hydrochloride (1.15 g, 6 mmol), HOBt (0.61 g, 4.5 mmol), DMA (15 mL) and dichloromethane (15 mL). The resulting residue was purified by silica gel column chromatography (elution solvent: ethyl acetate/hexane=1/4, 2/3, 3/2, 4/1) to obtain 0.89 g of the title compound as a colorless solid (77%).
