Procedure

Procedure C′: 2′-trifluoromethyl-biphenyl-4-carbaldehyde (Array 4PNL-S04-0) (0.63 g, 2.5 mmol) is suspended in formic acid (3.5 mL), and the solution is placed in an ice bath. Hydrogen peroxide is added (0.875 mL, 7.5 mmol), and the reaction vessel is placed in the refrigerator and is allowed to stand for 1-2 days. The yellow solid that precipitates out is filtered, washed with cold water and dried in a vacuum oven to give the title compound (0.45 g, 69%). MS (ES−) 265.1
