実験手順

A little at a time, 2.36 g of trimethyloxonium tetrafluoroborate are added to a solution of 3.52 g of 1-acetyl-3-[1-hydroxy-1-(3-iodophenyl)methylene]-6-chloro-2-indolinone (starting material VI) and 2.72 ml of ethyldiisopropylamine in 80 ml of dichloromethane, and the mixture is stirred at room temperature for one hour. Another 1.4 ml of ethyldiisopropylamine and 1.2 g of trimethyloxonium tetrafluoroborate are added, and the mixture is stirred at room temperature for another two hours. The mixture is then extracted with water and the organic phase is dried over magnesium sulphate and evaporated to dryness. The residue is recrystallized from ether and dried at 80° C. under reduced pressure.
