Methyl-4-hydroxy-3-chlorobenzoate (10 g, 53.6 mmol) and potassium carbonate (14.8 g, 107.2 mmol) were suspended in DMF (110 ml) and then ethyl iodide (8.56 ml, 107.2 mmol) was added. The reaction mixture was heated to 70° C. overnight. The reaction mixture was filtered and the residue washed with ether. The organic solutions were evaporated in vacuo and then dissolved in EtOAc and washed with aq. NaOH and water, dried and evaporated to dryness in vacuo to afford the title compound (11.24 g) as a yellow oil. MS (ES): C10H1135ClO3 requires 214; found (MH+) 215.
