Side chain chlorination
Web1. A method of chlorinating alkyl side chains of nitrogen heterocycles consisting essentially of reacting an α-alkyl side chain quasi aromatic nitrogen heterocycle in an inert solvent with trichloroisocyanuric acid at 20° to 200° C. whereby the side chain carbon atom attached to the nitrogen heterocycle is chlorinated.
