Reaction Steps

Aluminum chloride (1.4 g, 10.5 mmol) was added to a mixture of 3-(2,6-dichloro-phenyl)-1H-pyrrole (2 g, prepared as described in Journal of Organic Chemistry, 62: 2650 (1997) (incorporated herein by reference) and 2-chloronicotinoyl chloride (1.8 g, 10.5 mmol) in DCM (55 mL) at 0° C. The mixture was stirred at 0° C. for 30 mins and at room temperature for 1.5 hours. The reaction was diluted with ethyl acetate and washed with brine, 2N NaOH, brine, dried and concentrated. The residue was purified on silica gel column to give 168 mg of (2-chloro-pyridin-3-yl)-[4-(2,6-dichloro-phenyl)-1H-pyrrol-2-yl]-methanone.
