Reaction Steps

[step 2] Ethyl 2-(8-bromo-3-fluorodibenzo[b,e]oxepin-11(6H)-ylidene)-2-fluoroacetate (1.6 g, 4.05 mmol) obtained in step 1 was dissolved in THF (14 mL), 2 mol/L ammonia methanol solution (20 mL, 40.5 mmol) was added, and the mixture was stirred at 55° C. overnight. The mixture was concentrated under reduced pressure and the obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate=2/1 v/v) to give 2-(8-bromo-3-fluorodibenzo[b,e]oxepin-11(6H)-ylidene)-2-fluoroacetamide (910 mg, 61%).
