Versuchsvorschrift

Boron trifluoride-ether complex (0.36 ml, 2.94 mmol) was added dropwise at 0° C. to a solution of 4,4'-bis(methoxymethoxy)benzhydrol (8.96 g, 29.43 mmol) and 1-(2-chlorophenyl)-4-(indol-2-ylcarbonyl)piperazine (10.0 g, 29.43 mmol) in 200 ml of methylene chloride, followed by stirring at 0° C. to room temperature for 2 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 a crude product. The obtained crude product was recrystallized from ethanol to, give 15.1 g (yield: 82%) of the title compound.
