Banks, Ronald Eric published the artcileFluorocarbon derivatives of nitrogen. Part 11. Synthesis of some 2-(trifluoromethyl)imidazo[1,2-a]pyridines from trifluoroacetonitrile, Related Products of pyridine-derivatives, the publication is Journal of Fluorine Chemistry (1984), 26(4), 499-506, database is CAplus.
The title compound (I; R = Me3CO2C), prepared from CF3CN and pyridinium t-butoxycarbonylmethylide, reacts smoothly with CF3CO2H to give the acid (I; R = HO2C), which was decarboxylated to I (R = H) on heating. The cyano derivative (I; R = cyano) can be obtained via treatment of CF3CN with pyridinium cyanomethylide, which is sufficiently reactive to effect nucleophilic displacement of fluorine from pentafluoropyridine under mild conditions to give II.
