Reaction Steps
A solution of 4.4 g of ethyl 2-bromo-3-(4-methylphenyl)-3-oxopropanoate in 30 ml of anhydrous ethanol is added with 1.4 g of thioacetamide and the mixture is refluxed for 4 hours. The solvent is evaporated and the residue is dissolved in H2O and alkalinized to pH 10 with 10% NaOH, extracted 2 times with ether and the organic phase is washed with brine, dried and evaporated to dryness under reduced pressure. The residue is purified by F.C. (eluent 90:10 hexane:ethyl acetate) and 1.65 g of a light yellow solid are obtained (41% yield). 1H NMR (CDCl3), δ: 1.28 (t, 3 H), 2.39 (s, 3 H), 2.73 (s, 3 H), 4.26 (q, 2 H), 7.23 (d, 2 H), 7.62 (d, 2 H).
