Versuchsvorschrift

To a stirred solution of 84.0 g (0.744 mol) of N-(2-aminoethyl)-N-methyl-1,2-ethanediamine (see U.S. Pat. No. 3,201,472 for a method of obtaining this compound) in 700 ml of tetrahydrofuran was added 88.6 g (0.372 mmol) of 1-(3,5-diamino-6-chloropyrazinoyl)imidazole in 10 portions over 1 5 h. After 1 h at ambient temperature the reaction mixture was filtered and concentrated to 300 ml. The solution was added dropwise to 1.4 liters of ether with vigorous stirring. The solid was filtered, washed with ether and dried. There was obtained 74.3 g (0.258 mol, 70%) of 3,5-diamino-N-[2-[(2-aminoethyl)methylamino]ethyl]-6chloropyrazinecarboxamide. A sample was filtered through a pad of silica gel and eluted with 5:95 (v/v) methanol:methylene chloride saturated with ammonia gas mp 138°-139.5° C.
