A metallation reaction of the C-H bond in the methyl group of 3-methyl-4-phenylsydnone has been found to proceed on the action of n-buthyllithium. Subsequent reactions of 3-lithiomethyl-4-phenyl-sydnone thus obtained with electrophiles provide a convenient method for preparation of functionalised sydnones.
