Procedure

To a solution of 1-(4-methylphenyl)pyrrole (1 g) in tetrahydrofuran (50 ml) was added N-chlorosuccinimide (850 mg) in one portion at -78° C. under nitrogen atmosphere. The mixture was warmed to 10° C., stirred for one hour, and then concentrated in vacuo. The residue was purified by flash column chromatography on silica gel to yield 2-chloro-1-(4-methylphenyl)pyrrole (1.2 g) as an oil. (This product was a mixture of the starting material and the desired product and used to the next reaction furthermore without purification.)
