Potassium Cyanide → 4-Acetyl-6-chloro-3-ethoxy-2-iodobenzonitrile

Participants

Reaction Steps

A solution of 1-(5-chloro-2-ethoxy-4-fluoro-3-iodophenyl)ethanone (1.0 g, 2.9 mmol, from Example 211, Step 1) and potassium cyanide (0.29 g, 4.4 mmol) in DMF (11 mL) was stirred at 40° C. for 3 hours. The reaction mixture was diluted with water (100 mL) and extracted with EtOAc (2×75 mL). The combined organic layers were washed with brine, dried over sodium sulfate, filtered, and concentrated to a crude orange oil. The crude material was dissolved in 1:1 hexane/dichloromethane and purified by flash column chromatography using EtOAc in hexanes (0%-30% over 30 min) to give the desired product (0.79 g, 77%). LCMS for C11H10ClINO2 (M+H)+: m/z=349.9. Found: 349.9.
