실험 절차

A suspension of 4-fluorobenzonitrile (167 g, 1.38 mol), ethylenediamine (330 g, 5.5 mol) and potassium carbonate (300 g, 2.17 mol) in 2 1 of toluene is refluxed for 6 hours. After cooling to room temperature, the mixture is filtered and rinsed with toluene, and the filtrate is evaporated to give a yellow oil which is crystallized from toluene. The product is filtered off, rinsed with toluene and dried under vacuum at 50° C. to give 200 g of a slightly yellow solid.
