Reaction Steps
Methyl 3-fluoroisonicotinate was oxidized with 3-chloroperbenzoic acid, followed by heating in the presence of phosphoryl chloride. The product was separated by silica gel column chromatography to obtain methyl 2-chloro-5-fluoroisonicotinate (EI: 189) and methyl 2-chloro-3-fluoroisonicotinate (EI: 189).
