Synthesis under moderate pressure of 3-imidazo[1,2- a ]pyridinylidene pyrrol-2-ones

Conversion of 3-imidazo[1,2-a]pyridinylidene furan-2-ones into their pyrrol-2-one analogues was achieved efficiently with high yields, using a solution of ammonium hydroxide under moderate pressure conditions. A NMR study showed that the compounds are mainly isolated as E isomers.
