Chloroform → HCID 54381456, compound

Participants

Reaction Steps

In 10 ml of methylene chloride were dissolved 140 mg (0.54 mmole) of 2-(3-benzoyl-2,5-dimethylpyrrol-1-yl) 2-methylethanol and 383 mg (2.75 mmoles) of benzoyl chloride. Triethylamine (1 ml) was added to the solution, and the mixture was stirred at room temperature for 20 hours. Chloroform was added to the reaction mixture. The mixture was washed with dilute hydrochloric acid and then with an aqueous solution of sodium hydrogen carbonate, and the resulting extract was dried over anhydrous magnesium sulfate, and concentrated to afford 860 mg of a crude product. The product was chromatographed on a column of silica gel using cyclohexane/ethyl acetate (3/1) as an eluent to afford compound (314) (150 mg, 0.42 mmole, 77.8%).
