실험 절차

Triethyloxonium tetrafluoroborate (2.35 g) is added to a solution of (3aRS,7aRS)-7,7-diphenyl-2-[(2-methoxyphenyl)acetyl]perhydro-4-isoindolone (5 g) in dichloromethane (10 cc). The reaction mixture is left stirring for 20 hours at room temperature; it is then treated with ether (100 cc) and the precipitate obtained is drained, washed with ether (100 cc) and dried. (3aRS,7aRS)-2-[1-Ethoxy-2-(2-methoxyphenyl)ethylidene]-4-oxo-7,7-diphenylperhydroisoindolium tetrafluoroborate (5.75 g) is obtained in the form of a yellow powder, which is used in the crude state for the following manipulation.
