Reaction Steps

Aluminum chloride (1.7 g, 12.75 mmol) in dichloromethane (100 mL) was added to the 3,4-dimethoxybenzoyl chloride (2.0 g, 10 mmol) at room temperature, followed by a solution of 2,4-dimethylpyrrole (1.5 g, 15.8 mmol) in dichloromethane (5 mL). The mixture was then stirred at room temperature for overnight. The reaction was diluted with ethyl acetate, washed with brine, dried and concentrated. The residue was chromatographed eluting with ethyl acetate and hexane to give 1 g (39%) of (3,4-dimethoxy-phenyl)-(3,5-dimethyl-1H-pyrrol-2-yl)-methanone as a solid.
