To a suspension of N-(5-chloro-2-cyanophenyl)benzamide (150 mg, 0.58 mmol) in H2O (5 mL) was added in sequence NaOH (100 mg, 2.5 mmol) and H2O2 (30% in H2O, 0.25 mL, 2.2 mmol). The reaction was heated to 80° C. for 24 h then cooled to rt and stirred at rt for 1 d. Aq HCl (2 M, 6 mL) was added forming a thick precipitate that was collected by a filtration. The filter cake was washed with H2O several times affording the title compound as a creamy-white solid; MS (ES+): m/z 257.1 (100) [MH+]; HPLC: tR=3.34 min (OpenLynx, polar—5 min).
