Reaction Conditions

Reaction Steps

2-(5-methyl-1H-pyrazol-1-yl)pyridine (100 mg, 0.63 mmol) and N-iodosuccinimide (212 mg, 0.942 mmol) were added to acetonitrile (5 ml). The reaction mixture was heated to 60° C. After 1 hour, the reaction mixture was diluted with ethyl acetate, washed with 1N aqueous sodium hydroxide and brine, then dried over magnesium sulfate, filtered, and concentrated. The residue was purified by column chromatography on silica gel (ethyl acetate/isohexane gradient) to afford 2-(4-iodo-5-methyl-1H-pyrazol-1-yl)pyridine. LRMS (ESI) calculated for C9H9IN3 [M+H]+, 286.0; found 286.0.
