Versuchsvorschrift
A solution of 4-amino-2-[2-(3-cyano-2-methylisothioureido)ethylthiomethyl]pyrimidine (0.75 g.) in 33% w/v methylamine in ethanol (15 ml.) was left at room temperature for 18 hours. The solution was concentrated to 5 ml., cooled in ice, and the crystalline precipitate collected to give 4-amino-2-[2-(2-cyano-3-methylguanidino)ethylthiomethyl]pyrimidine (0.52 g.), m.p. 189°-190°.
