Participants

Reaction Steps

Prepared by a method analogous to that described for the preparation of (2′R)-5′-(furan-3-yl)spiro[1-azabicyclo[2.2.2]octane-3,2′(3′H)-furo[2,3-b]pyridine] in Preparation 1 from (2′R)-5′-bromospiro[1-azabicyclo[2.2.2]octane-3,2′(3′H)-furo[2,3-b]pyridine] and benzofuran-2-boronic acid. The compound was purified by flash chromatography using a gradient of ammoniated methanol in chloroform and obtained as a pale solid; m/z 333 (100%, MH+).
