Procedure

To a solution of 1.00 g (4.72 mmol) of 2-hydroxy-5-methylbenzophenone and 1.19 g (5.19 mmol) of methyl 2-bromophenylacetate in 10 mL of acetone was added 1.30 g (9.44 mmol) of K2CO3 and the mixture was stirred and refluxed for 14 hours. The mixture was cooled, filtered and evaporated in vacuo and the residue was purified on a silica gel flash chromatography column eluted with 5% ethyl acetate/hexane to afford 0.320 g (19%) of the title compound.
