Methyl iodide → HCID 12603267, compound

Participants

Reaction Steps

Sodium hydride (50% content, 115 mg, 2.3 mmoles) was washed with 20 ml of petroleum ether twice, and 15 ml of dimethoxyethane was added. To the mixture was added 300 mg (1.17 mmoles) of 2-(3-benzoyl-2,5-dimethylpyrrol-1-yl)-2-methylethanol, and the mixture was stirred at room temperature for 2 hours. Then, 5 ml of methyl iodide was added, and the mixture was further stirred at room temperature for 5 hours. After the reaction, the reaction mixture was extracted with ethyl acetate. The organic layer was washed with water, dried over anhydrous magnesium sulfate, and concentrated to afford 270 mg of a crude product. The product was chromatographed on a column of silica gel using cyclohexane/ethyl acetate (4/1) as an eluent to afford compound (206) (220 mg, 0.81 mmole, 69.4%).
