Reaction Steps

To a solution of 2-acetylamino-4-fluoromethyl-benzoic acid methyl ester (1.5 g, 6.66 equiv) in MeOH (50 mL) was added concd sulfuric acid (4 mL) and the mixture was refluxed for 1 h. The mixture was cooled down and concentrated in vacuo. Water was added and the pH was adjusted to 9-10 by addition of 2N NaOH. The aqueous phase was extracted with AcOEt. The organic phase were combined, washed with brine and dried (Na2SO4). The solution was concentrated in vacuo to afford the title compound as a yellow-orange oil (1.24 g, 100%) (ES-MS: m/z 184.1 [M+H]+, rt 4.91 min).
