Anodic fluorinations of ethyl isonicotinate (1) and related compounds have been attempted. Desired fluorinated product, 2-fluoroisonicotinate (2) was obtained in reasonable yield by direct anodic monofluorination of ethyl isonicotinate 1. The yield of 2 and the conversion of the electrochemical reaction could be improved by applying relatively lower anodic potential and by increasing the concentration of supporting electrolyte Et3N . 3HF.
