Reaction Steps

The same operation as in Example (1g) was performed using ethyl cis(±)-2-(4-amino-3-methoxypiperidin-1-yl)-1,3-thiazole-5-carboxylate obtained by the method described in Example (5d) (0.22 g, 0.77 mmol), 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid obtained by the method described in Example (1d) (85 mg, 0.49 mmol), WSC hydrochloride (0.56 g, 2.92 mmol) and DMAP (0.13 g, 1.02 mmol), to obtain 0.15 g of the title compound as a pale yellow solid (71%).
