Reaction Steps

A mixture of 2-hydroxy-3-methoxybenzaldehyde (3.04 g), ethyl 2-bromopropionate (5.85 g), and potassium carbonate (4.14 g) in dimethylsulfoxide (20 ml) was stirred at 70° C. for 5 hours. The mixture was diluted with water, neutralized with 1N hydrochloric acid, and was extracted with ethyl acetate. The organic layer was separated, washed with brine, dried over magnesium sulfate, and concentrated. The crude product (0.93 g) was purified on a silica gel column (60 g) eluting with a mixed solvent of n-hexane and toluene (from 6:1 to 5:1) to give ethyl 2-(2-formyl-6-methoxyphenoxy)-propionate (5.25 g).
