Reaction Steps

Into a Round bottom flask was added Ethanone, 1-(2-hydroxy-4-methoxyphenyl)-ethanone (40.01 g, 0.241 mol), ethyl bromoacetate (28.17 mL, 0.2540 mol), potassium carbonate (69.6 g, 0.504 mol), and N,N-Dimethylformamide (200 mL, 2 mol). The reaction was heated at 90° C. for 6 h before cooling to RT overnight. The reaction was poured into ice/water and extracted with ethyl ether (twice). The combined ether extracts were dried, filtered and concentrated. The resulting solid was triturated in hexanes, filtered and dried. The product was used in the next reaction step without further purification.
