Reaction Steps

Alternatively, the compound is obtained as follows: a solution of trifluoroperacetic acid (prepared from 1.8 ml of 85% strength hydrogen peroxide, 17 g of trifluoroacetic anhydride and 15 ml of methylene chloride) is added dropwise to a boiling mixture of 9.5 g of 5-phenyl-2-methylenevaleric acid and 28 g of disodium hydrogen phosphate in 50 ml of methylene chloride. The mixture is boiled under reflux for a further 30 minutes; 150 ml of ice-water are added; *the organic phase is separated off and, after drying over sodium sulfate, is concentrated. The title compound remains as a viscous oil.
