실험 절차

The same operation as in Example (77d) was performed using ethyl cis(±)-2-(3-amino-4-{[(4-chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}piperidin-1-yl)-1,3-benzothiazole-7-carboxylate obtained by the method described in Example (81e) (37 mg, 0.071 mmol), cyclopropanecarbaldehyde (6.5 μL, 0.087 mmol) and sodium (triacetoxy)borohydride (44 mg, 0.21 mmol), to obtain 35.3 mg of the title compound as a white solid (93%).
