Reaction Steps

2-Chloro-4-iodo-6-(trifluoromethyl)pyridine (0.50 g, 1.5 mmol, prepared according to the method described in European Journal of Organic Chemistry, (18) 3793-3798; 2004) and copper cyanide (0.52 g, 5.8 mmol) were mixed in N-methylpyrrolidinone (2 mL). The reaction vial was sealed and heated in the microwave to 120° C. for 10 minutes. The mixture was diluted with water and EtOAc and was filtered. The organic layer was washed with water (3×), followed by brine, dried over sodium sulfate and concentrated. Flash chromatography on silica gel, eluting with a gradient from 0-15% EtOAc in hexanes afforded product as a colorless oil (0.24 g, 64%).
