Conditions

Temperature
110 °C

Procedure

Concentrated hydrochloric acid (37%, 1 mL) is added to a solution of (4′-trifluoromethyl-biphenyl-4-yl)-acetonitrile (0.290 g, 1.11 mmol) in [1,4]dioxane (2 mL), heated at 110° C. for six hours, cooled to room temperature and adjust pH to 3 using 5.0 N sodium hydroxide, extracted with ethyl acetate three times. Organics are dried over sodium sulfate, filtered and concentrated to provide 0.280 g (11.0 mmol, 90%) of title compound.
