4-Methylbenzoyl Chloride → (1-benzenesulfonyl-1H-pyrrol-2-yl)(4-methylphenyl)ketone

Participants

Reaction Steps

Under nitrogen atmosphere, to a suspension of aluminum chloride (4.62 g) in dichloroethane (50 mL) was added a solution of p-toluoyl chloride (4.91 g) in dichloroethane (5 mL) at room temperature over a period of 10 minutes. After stirring for 30 minutes, to the mixture was added a solution of 1-benzenesulfonyl-1H-pyrrole (6.00 g) in dichloroethane (10 mL) over a period of 10 minutes. The mixture was stirred at room temperature for 2 hours, and the reaction mixture was poured into ice water, and the aqueous layer was extracted twice with methylene chloride. The organic layers were combined, dried, filtered and concentrated. The residue was purified by silica gel column chromatography to give (1-benzenesulfonyl-1H-pyrrol-2-yl) (4- methyl-phenyl) ketone (9.9 g, 100%).
