To a mixture of methyl 5-iodo-2-methoxy-4-methylbenzoate (3.0 g, 9.80 mmol) in ethanol (10 ml) in a 50 ml RB flask was added an aqueous solution of NaOH (0.784 g, 19.60 mmol, 1M). The reaction mixture was stirred at room temperature overnight. The solvent was removed under vacuum, the solid filtered and dried to give the titled compound (2.2 g, 74%). LCMS: (ES+) m/z=292 (M+H)+; Column.
