2-Bromo-4'-methylacetophenone → HCID 12335292, compound

Participants

Reaction Steps

A mixture of 2-pyridyl acetonitrile (5.0 g) and 2-bromo-4'-methylacetophenone (8.52 g) in acetone (10 ml) was heated at 80° C. for 24 hours, during which 2-pyridylacetonitrile (1 g, 2 g) was added to the reaction mixture. After being cooled, the solvent was removed in vacuo and the residue was chromatographed on silica gel eluted with a mixture of ethyl acetate and n-hexane (1:6 to 1:2, V/V) to give a solid product. This product was recrystallized from ethanol-water to give 2-(4-methylphenyl)indolizine-1-carbonitrile (4.1 g) as a pale brown powder.
