1-Phenylsulfonylpyrrole → (1-benzenesulfonyl-1H-pyrrol-2-yl)-(2-chloro-pyridin-3-yl)-methanone

Participants

Reaction Steps

To a solution of 2-chloro-nicotinoyl chloride (1.17 g) (Aldrich, Milwaukee, Wis.) and 1-benzensulfonyl-1H-pyrrole (1 g) (Aldrich) in dichloroethane (15 mL) was added aluminum chloride (1.1 g). After stirring at room temperature for one hour, the reaction was diluted with ethyl acetate, washed with water, base and brine, dried and purified to give 820 mg of (1-benzenesulfonyl-1H-pyrrol-2-yl)-(2-chloro-pyridin-3-yl)-methanone.
