実験手順

2-Amino-5-methoxy-4-methylbenzoic acid (2.7 g, 14.9 mmol, 61%) and aqueous hydriodic acid (40%, 80 mL) were heated at reflux for 36 h. The aqueous was evaporated under vacuum and the residue washed with ether to yield 2-amino-5-hydroxy-4-methylbenzoic acid (INTERMEDIATE V.1) (2.5 g, 14.9 mmol 100%)
