Product 1

HCID 686641093-(2,5-Difluorophenyl)-5-(5-methyl-1,3,4-oxadiazol-2-yl)furo[3,2-b]pyridineYield 43%

Procedure

In the same manner as in Example 132 and using 3-bromo-5-(5-methyl-1,3,4-oxadiazol-2-yl)furo[3,2-b]pyridine instead of 2-(3-bromo-1-benzofuran-5-yl)-5-methyl-1,3,4-oxadiazole, using (2,5-difluorophenyl)boronic acid instead of (4-fluorophenyl)boronic acid, and using [1,1′-bis(diphenylphosphino)ferrocene]palladium(II) chloride dichloromethane complex instead of tetrakis(triphenylphosphine)palladium(0), the title compound (yield 43%) was obtained as colorless crystals.
