Procedure

Combine 4-(4-Formyl-phenoxy)-benzonitrile (3.6 g, 16.1 mmol), dimethylsufoxide (25 mL), potassium carbonate (2.1 g, 15.2 mmol), and 3 mL of 30% hydrogen peroxide solution. Stir 18 h at ambient temperature. Dilute with 100 mL of water, extract with ethyl acetate (3×100 mL). Wash the organic phase with 100 mL of water, and 50 mL of brine. Dry the organic phase over sodium sulfate, filter, and concentrate under vacuum. Purify via aBiotage Flash 40L system using 75:25 hexanes/ethyl acetate as eluting solvent to give 3.0 g (77%) of the title compound: 1H NMR (chloroform-d): 9.95 (s, 1H), 7.88 (m, 4H), 7.12 (m, 4H), 5.29-5.14 (br m, 2H).
