Procedure

A mixture of 1-(3-carbomethoxy-4-hydroxyphenyl)propan-2-one (3.0 g), iodomethane (5.0 g), potassium carbonate (7.0 g) was refluxed in acetone until tlc showed no starting material (~6 hours). The mixture was cooled, filtered and evaporated. The residue was partitioned between ether and water and the layers separated. The ether layer was dried (MgSO4) and evaporated to give the title compound (3.2 g). τ (CDCl3) 7.84 (3H, s), 6.35 (2H, s), 6.1 (3H, s), 3.05 (1H, d, J=8 Hz), 2.68 (1H, dd, J=8 Hz, J=2 Hz), 2.36 (1H, d, J=2 Hz).
