실험 절차

33 g of the sodium salt of N,N'-dicyano-cyclopropanecarbamidine (crude product) is suspended in 100 ml butanone. A solution of 20 g HCl in 400 ml butanone is dropped under stirring into this solution at 10° C. After the addition has been completed it is stirred for 1 h at ambient temperature. The reaction mixture is concentrated by evaporation and 200 ml of saturated aqueous NaHCO3 -solution and 300 ml diethylether are added. The organic phase is separated, washed, dried and concentrated by evaporation. One isolates 21 g of crude product which is treated with hexane to leave the pure title product.
