Procedure

Benzoyl peroxide (0.91 g, 0.037 mol) is added to diethyl 1-methoxypyrrolo[3,2-b]pyridine-5,6-dicarboxylate (1.0 g, 0.003 mol) dissolved in (40 mL) carbon tetrachloride under a nitrogen atmosphere and the suspension stirred for ten minutes. N-Chlorosuccinimide (0.84 g, 0.0063 mol) is then added and the reaction heated at 60° C. for four hours. The mixtue is cooled to room temperature and the inorganics are removed by filtration. The organic mother liquors are washed with water and sodium bisulfate and concentrated in vacuo to an orange oil. The oil is flash chromatographed using hexanes and then 4:1 hexanes/ethyl acetate, giving the title product as an off-white solid in 51% yield, having a melting point 146°-148° C.
