Hydrochloric Acid → HCID 12902852, compound

Participants

Reaction Steps

A mixture of 64 g. (0.18 mole) of the product of step B, 17.8 g. (0.2 mole) of cuprous cyanide and 35 ml. of pyridine is heated under a nitrogen atmosphere at 150° to 160° C. for one day. The mixture is poured into 1 liter of 3 N hydrochloric acid, extracted with 1 liter of dichloromethane, and the extracts are dried. Evaporation provides a residue which is chromatographed on silica gel, eluting with dichloromethane, to provide 7-cyano-3,5-diphenylbenzofuran as a pale yellow solid. The structural assignment is supported by infrared and nuclear magnetic resonance spectral analysis.
