関与物質

反応手順

A mixture of 2.0 g of 3-fluoro-4-hydroxybenzeneacetic acid, 10 ml of methyl alcohol and 1 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 water, saturated sodium bicarbonate, water and saturated sodium chloride; dried and concentrated in vacuo. The residue is purified by column chromatography (silica gel:25% ethyl acetate/hexane) to give 1.9 g of the desired product.
