Procedure

A mixture of 2-(2-chloro-6-iodophenyl)acetonitrile (10 g, 36 mmol) in 20 mL dioxane was treated with 25 mL 9M H2SO4. The mixture was stirred at 115° C. for 2 hours. The mixture was transferred into a sealed tube and heated to 150° C. and stirred for 2 hours. The mixture was then 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 sodium sulfate, and concentrated to give crude product 10.3 g as pale yellow solid. MS m/e: (M+H)+ 297.
