Procedure

Methylchloroacetate (9.4 g, 86.66 mmol) was added dropwise to a mixture of salicylic acid (10 g, 72.46 mmol) and triethylamine (8.8 g, 86.96 mmol) in acetone (50 ml) and heated to reflux for 10 hrs. Solids were filtered off and potassium carbonate (25 g, 180.89 mmol) was added to the acetone layer together with sodium iodide (2 gm, 13.34 mmol), disodium phosphate (2 g, 14.16 mmol) and methylchloroacetate (9.4 g, 86.66 mmol) and refluxed for 16 hrs. Acetone was distilled off and water (125 ml) added. Crude 93 was extracted into chloroform, washed with 5% sodium bicarbonate solution (2×50 ml), with water (2×50 ml), dried over sodium sulphate and distilled. Crude 93 was purified by column chromatography on silica gel using benzene to get pure 93 (12 g, 58.7%) as a syrup.
