実験手順

A solution of 4-amino-2-hydroxybenzoic acid (1 g, 6.5 mmol) in MeOH (15 mL) and concentrated sulfonic acid (1 mL) was refluxed overnight. The reaction mixture was quenched with NaHCO3 aqueous solution (60 mL) and EtOAc (60 mL). The organic layer was separated, dried, evaporated to give 3-hydroxy-4-methoxycarbonylaniline.
