실험 절차
To (E)-[2-(2-propylbenzimidazol-1-yl)methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5-ylidene]acetohydrazide (27 mg, 0.062 mmol) obtained in Example 7, step 1 was added triethyl orthoformate (0.5 mL), and the mixture was stirred at 120° C. for 20 hr. The mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=70/30 to 0/100) to give the title compound (compound 11) (26 mg, 93%).
