Conditions

Temperature
40 °C

Procedure

4-Acetamidomethylbenzoic acid (4.0 g) was dissolved in 0.5% hydrogen chloride-methanol solution (100 ml). The mixture was stirred at 40° C. for 3.5 hr and poured into ice water (300 ml) and extracted with ethyl acetate. The extract was washed with a saturated aqueous sodium hydrogencarbonate solution and saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated to give a pale-yellow solid (4.3 g). The obtained solid was crystallized from ethyl acetate (50 ml) to give the title compound (3.2 g) as a pale-yellow white crystals, m.p.=110-111° C.
