Potassium Iodide → Methyl 4-(2-oxopropoxy)benzoate

Participants

Reaction Steps

A mixture of methyl 4-hydroxybenzoate (30.4 g), chloroacetone (8.5 g) potassium carbonate (54 g) and potassium iodide (33.3 g) was refluxed in acetone for 4 hours. The reaction mixture was cooled, the solids filtered and the solvent evaporated. The residue was partitioned between water and ether, the layers separated and the organic layer dried (MgSO4). Removal of the solvent gave the title compound (36 g). τ (CDCl3) 7.75 (3H, s), 6.11 (3H, s) 5.39 (2H, s), 3.09 (2H, d, J=9 Hz), 2.0 (2H, d, J=9 Hz).
