Reaction Steps

A mixture of 3-(4-amino-3-propylaminomethyl-phenoxy)-benzonitrile (0.032 mol) in ethanol (400 mL) was stirred at room temperature, and cyanogen bromide (0.038 mol) was added, and then the reaction mixture was stirred and refluxed for 2 hours. After cooling, the precipitate was filtered off, washed with diisopropyl ether and dried to yield crude product as a solid.
