Reaction Steps
A mixture of 50 g of 3-chloro-4-hydroxybenzeneacetic acid, 250 ml of methyl alcohol and 10 ml of concentrated sulfuric acid is heated at reflux temperature for 23.5 hours. The cooled solution is diluted with water and extracted with methylene chloride. The organic layer is washed with saturated sodium bicarbonate and saturated sodium chloride, dried and concentrated in vacuo. The residue is purified by column chromatography (silica gel:30% ethyl acetate/hexane) to give 49.9 g of the desired product.
