Reaction Steps

A solution of 3-(2-pyridyl)-5-(3-bromomethyl-5-cyanophenyl)-1,2,4-oxadiazole (0.5 g, 1.91 mmol) in dichloromethane (1.5 mL) was treated with a 0.5M ammonia (1.5 mL, 1.5 mmol, dioxane) and heated at 50° C. for 90 minutes. After this time the reaction mixture was cooled and diluted with dichloromethane. The organic solution was washed with water and brine. Silica gel chromatography of the crude product afforded 3.5 mg (5.5%) of 3-(2-pyridyl)-5-(3-aminomethyl-5-cyanophenyl)-1,2,4-oxadiazole.
