Reaction Steps
LiOH (1M, 4 mL) was added to a solution of 2-(4-fluoro-benzoylamino)-4-methoxy-3-methyl-benzoic acid methyl ester (90) (870 mg, 2.7 mmol), in tetrahydrofuran (15 ml), water (7.5 ml) and methanol (7.5 ml). The mixture was heated to 50° C. for 4 h. Water (30 ml) was then added and the volume reduced to half. Acidification with acetic acid followed by filtration gave pure title compound (830 mg, 100%).
