Versuchsvorschrift

Fifty-four (54) mg of methyl 3,3,3-tris(4-vinylphenyl)-propionate was suspended in 0.5 ml of dioxane, and to the suspension 0.5 ml of 4N aqueous lithium hydroxide solution was added at room temperature, followed by 17 hours' stirring at 90° C. under heating. The reaction liquid was made acidic by addition of 1N hydrochloric acid, extracted with chloroform and dried over anhydrous sodium sulfate. Distilling the solvent off under reduced pressure, 52.5 mg of the title compound was obtained.
