Reaction Steps

A mixture of 3-(2-pyridyl)-5-(3-cyano-5-methylphenyl)-1,2,4-oxadiazole (0.5 g, 1.91 mmol), N-bromosuccinimide (0.339 g, 1.91 mmol), and benzoyl peroxide (0.0010 g, 0.04 mmol) in carbon tetrachloride (25 mL) was heated at 80° C. for 18 hours. After this time the reaction mixture was cooled and diluted with dichloromethane. The organic solution was washed with water and brine to afford 0.595 g (91%) of 3-(2-pyridyl)-5-(3-bromomethyl-5-cyanophenyl)-1,2,4-oxadiazole.
