실험 절차

[step 1] Ethyl 3-oxohexanoate (883 mg, 5.58 mmol) was dissolved in THF (9 mL), sodium hydride (60% w/w, 190 mg, 4.75 mmol) was added, and the mixture was stirred at room temperature for 30 min. To the mixture was added dropwise a solution (9 mL) of (E)-2-[8-(bromomethyl)-3-fluorodibenzo[b,e]oxepin-11(6H)-ylidene]propanenitrile (1.0 g, 2.79 mmol) obtained in Reference Example 1 in tetrahydrofuran, and the mixture was stirred at room temperature overnight. Water was added to the mixture, and the mixture was extracted 3 times with ethyl acetate. The combined organic layers were dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=4/1 v/v) to give (E)-ethyl 2-{[11-(1-cyanoethylidene)-3-fluoro-6,11-dihydrodibenzo[b,e]oxepin-8-yl]methyl}-3-oxohexanoate (1.19 g, 98%).
