Versuchsvorschrift

A mixture of 4-[3-(2,2,2-trifluoroethyl)thioureido]-2-methylthiopyrimidine (2.15 g.), methanol (100 ml.), saturated ethanolic ammonia (10 ml.) and yellow mercuric oxide (4.3 g.) was stirred at room temperature for 2 hours and then filtered. The filtrate was evaporated to dryness and the residue recrystallised from ethanol to give 4-[2-(2,2,2-trifluoroethyl)guanidino]-2-methylthiopyrimidine (1.5 g.), m.p. 201°-202°.
