実験手順

To a stirred solution of imidazo[1,2-a]pyridine-8-carbonitrile (1.2 g, 8.38 mmol) in dichloromethane (10 mL) was added N-iodosuccinimide (1.89 g, 8.38 mmol). LCMS monitored the reaction until the starting material consumed completely. The reaction mixture was diluted with dichloromethane and water. The separated organic layer was dried sodium sulfate, filtered and concentrated to give 3-iodoimidazo[1,2-a]pyridine-8-carbonitrile (1.8 g, 6.69 mmol, 80% yield) as a brown solid. MS (ES+) C8H8IN3 requires: 269. Found: 270 [M+H]+.
