A mixture of 0.50 g (2.65 mmol) of 3-chloro-4-hydroxy-5-methoxy-benzaldehyde, 0.668 g (2.92 mmol) of methyl 2-bromophenylacetate and K2CO3 (0.73 g, 5.3 mmol) in acetone (8 mL) was refluxed for 14 h. The mixture was cooled, filtered and evaporated in vacuo, and the residue was purified by flash chromatography on a silica gel column using 5% ethylacetate in hexane to afford 0.570 g (64%) of the title compound.
