Reaction Steps

Add 4-chloro-2-trifluoromethyl-benzonitrile to formic acid (96%) (15 mL) and water (3 mL). Add nickel-aluminum alloy (1260 mg). Heat at 100° C. overnight. Dilute with ethyl acetate and filter through Celite®. Extract the filtrate with 1 N sodium hydroxide and saturated aqueous sodium chloride, dry (sodium sulfate), filter, and concentrate to give 4-chloro-2-trifluoromethylbenzaldehyde (555 mg, 87%): 1H NMR (400 MHz, MeOH-d4) δ 10.29 (m, 1H), 8.10 (d, 1H, J=8.4 Hz), 7.91 (d, 1H, J=1.6 Hz), 7.85 (dd, 1H, J=8.4, 1.6 Hz).
