Reaction Steps

The same operation as in Example (217c) was performed using ethyl 2-[(3R)-3-aminopyrrolidin-1-yl]-4-methyl-1,3-thiazole-5-carboxylate obtained in Example (238a) (116 mg, 0.45 mmol), 4-chloro-5-ethyl-1H-imidazole-2-carboxylic acid obtained in Example (1d) (79 mg, 0.45 mmol), WSC hydrochloride (260 mg, 1.36 mmol), 1-hydroxybenzotriazole (61 mg, 0.45 mmol) and N-methylmorpholine (0.10 mL, 0.90 mmol), to obtain 155 mg of the title compound as a white solid (83%).
