Reaction Steps

[step 4] Using 8-(difluoromethoxy)-3-iodo-2-(methoxymethyl)imidazo[1,2-a]pyridine (700 mg, 1.98 mmol) obtained in step 3 and (E)-2-(3-fluoro-8-formyldibenzo[b,e]oxepin-11(6H)-ylidene)propanenitrile (290 mg, 0.988 mmol) obtained in Reference Example 5, and in the same manner as in Reference Example 8F, step 4, (E)-2-(8-{[8-(difluoromethoxy)-2-(methoxymethyl)imidazo[1,2-a]pyridin-3-yl](hydroxy)methyl}-3-fluorodibenzo[b,e]oxepin-11(6H)-ylidene)propanenitrile (400 mg, 78%) was obtained.
