Procedure

A suspension of 3-chloro-6-methylpyridazine (3 g), benzoyl peroxide (150 mg) and N-chlorosuccinimide (3.12 g) in CCl4 (30 ml) was refluxed 16 hours, cooled, filtered and evaporated. Chromatography (EtOAc/hexane) gave title compound (1.67 g). NMR δ(CDCl3) 4.87 (2H, s), 7.58 (1H, d), 7.71 (1H, d).
