Reaction Steps

4-Tolualdehyde (39.6 g, 0.33 mol) and 2M NaOH solution (230 ml) are added to a solution of levulinic acid (39.5 g, 0.34 mol) in EtOH (85 ml) over 1 hour. The resulting clear solution is poured into ice and acidified with 6M HCl. The resulting gum obtained is crystallised with acetone/water and recrystallised from CH2Cl2 to yield 14.0 g of 6-(4 methylphenyl)-4-oxo-hex-5-enoic acid as colourless crystals m.p. 129-130.
