(E)-[2-(2-Propylbenzimidazol-1-yl)methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5-ylidene]acetonitrile (404 mg, 1.00 mmol) obtained in Example 1 was dissolved in ethanol (8 mL), 2 mol/L aqueous sodium hydroxide solution (2 mL) was added, and the mixture was stirred at 70° C. for 2 days. Water was added to the mixture, and the mixture was extracted with chloroform. The organic layer was washed with 2 mol/L aqueous sodium hydroxide solution and brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. Ethyl acetate was added to the residue, and the mixture was filtered to give the title compound (compound 3) (279 mg, 66%).
