Reaction Steps

[step 2] 2-Cyclopropyl-2-{3-fluoro-8-[(trimethylsilyl)ethynyl]dibenzo[b,e]oxepin-11(6H)-ylidene}acetonitrile (1.0 g, 2.6 mmol) obtained in step 1 was dissolved in methanol (10 mL), potassium carbonate (0.35 g, 2.6 mmol) was added, and the mixture was stirred at room temperature for 1 hr. The reaction was discontinued with water, and the mixture was extracted 3 times with ethyl acetate. The combined organic layers were washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was crystallized from isopropyl ether and collected by filtration to give the title compound (600 mg, 74%, E/Z=1/1).
