反応手順
The same operation as in Example (1g) was performed using tert-butyl cis(±)-4-amino-3-ethoxypiperidine-1-carboxylate obtained by the method described in Example (112d) (0.48 g, 1.96 mmol), 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid obtained by the method described in Example (1d) (0.31 g, 1.51 mmol), WSC hydrochloride (0.88 g, 4.59 mmol) and HOBT (0.21 g, 1.51 mmol), to obtain 0.59 g of the title compound as a white foamy substance (91%).
