実験手順

Specifically, acetic anhydride (120 mL) was added to 30.0 g (165 mmol) homovanillic acid and the mixture was allowed to reflux for 6 hours. The solvent was evaporated, leaving an oil which was poured into 1L H2O and allowed to stir overnight. The solid was collected and dried in vacuo to give 33.1 g of 4-acetoxy-3-methoxyphenylacetic acid.
