실험 절차

A mixture of 2-(3-chloro-2-iodophenyl)acetonitrile (3.2 g, 12 mmol) in 20 mL dioxane was treated with 25 mL 9M H2SO4. The mixture was stirred at 115° C. for 2 hours, cooled to room temperature, and diluted with 100 mL water. The mixture was extracted with EtOAc (3×50 mL). The combined organic layers were washed with saturated NaCl (20 mL), dried over anhydrous sodium sulfate, and concentrated to give crude product in 4 g as pale yellow solid. MS m/e: (M+H)+ 297.
