2-(4-(3-Methyl-2-butenyl)phenyl)propionic acid → HCID 20291061, compound

Participants

Reaction Steps

4.8 g of 2-(p-prenylphenyl)propionic acid as prepared in Example 1 was dissolved in 5% aqueous sodium hydroxide solution to adjust to pH 9.0. To the solution, 5% aqueous calcium chloride solution was added dropwise until the insoluble calcium salt no longer formed. The aqueous layer was decanted and the residual solid was crystallized from methanol to give 4.2 g of calcium 2-(p-prenylphenyl)propionate, colorless needles, m.p. 64°-65° C.
