Friedel-Crafts acylations of 3-alkyl-1-(phenylsulfonyl)pyrroles appear to be kinetically favored at the adjacent C-2 position but rearrangement to the C-5 position can occur after prolonged reaction times. This reversible Friedel-Crafts methodology has been employed for the synthesis of the ant trail pheromone, methyl 4-methylpyrrole-2-carboxylate.
