Methanesulfonic Acid → HCID 15858911, compound

Participants

Reaction Steps

Benzhydryl acetate (2.2 g, 9.71 mmol) and 2-[4-(2-chlorophenyl)piperazinylcarbonyl]indole (3.0 g, 8.83 mmol) were dissolved in a mixed solvent of methylene chloride (50 ml) and chloroform (50 ml), and methanesulfonic acid (1.72 ml, 26.5 mmol) was added thereto, followed by stirring at room temperature for 3 hours. A saturated aqueous solution of sodium bicarbonate was added to the reaction solution for neutralization followed by extraction with chloroform. The resulting organic layer was washed with a saturated aqueous solution of sodium bicarbonate and a saturated aqueous solution of sodium chloride, and dried over magnesium sulfate, and the solvent was distilled off under reduced pressure to give 6.5 g of a crude product. The obtained crude product was washed with ethanol (60 ml) under heating to give 4.0 g (yield: 89%) of the title compound.
