Versuchsvorschrift

[step 1] 2-Ethyl-3-methylindole (196 mg, 1.23 mmol) was dissolved in DMF (3.2 mL), sodium hydride (60%; 49 mg, 1.23 mmol) was added, and the mixture was stirred at room temperature for 15 min. To the reaction mixture was added (E)-2-(2-bromomethyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5-ylidene)acetonitrile (200 mg, 0.617 mmol) obtained in Reference Example B1, and the mixture was stirred at room temperature for 2 hr. Water was added to the mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=9/1) to give (E)-[2-(2-ethyl-3-methylindol-1-yl)methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5-ylidene]acetonitrile (117 mg, 47%).
