実験手順

2-chloro-4-iodo-5-(trifluoromethyl)pyridine was dissolved in 7 M Ammonia/Methanol. It was heated in a Biotage Initiator microwave synthesizer at 130° C. for 1 h. A mixture of the 2- and 4-substituted products was obtained. The solvent was removed and the residue was purified by silica gel chromatography (DCM/MeOH) gradient. The pure title compound was isolated.
