실험 절차

Following the procedure described for 3,5-dichloro-4-(7-chloropyrazolo[4,3-c]pyridin-2-yl)benzonitrile, [1-(4-azido-5-bromopyridin-3-yl)-meth-(E)-ylidene]-(2,6-dichlorophenyl)-amine was heated under reflux in toluene to afford the title compound as a brown solid (7.5 g, 81% yield). LCMS (Method D): RT=2.90 min, m/z: 344 [M+H+].
