反応手順
The same operation as in Example (33c) was performed using ethyl cis(±)-2-(4-{[(4-chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}-3-ethoxypiperidin-1-yl)-4-formyl-1,3-thiazole-5-carboxylate obtained in Example (68b) (about 0.63 mmol), sodium chlorite (113 mg, 1.25 mmol), sodium dihydrogenphosphate (320 mg, 2.05 mmol) and 2-methyl-2-butene (0.33 mL, 3.12 mmol), to obtain 312.7 mg of the title compound as a white solid (99%).
