Reaktionsschritte
A mixture of 4-amino-2-[(2-phthalimidoethyl)thiomethyl]pyrimidine (5.9 g.), 2,2,2-trifluoroethylisothiocyanate (3.9 g.) and acetonitrile (20 ml.) was stirred at 70° for 72 hours. The reaction mixture was cooled and the crystalline precipitate collected to give 4-[3-(2,2,2-trifluoroethyl)thioureido]-2-[(2-phthalimidoethyl)thiomethyl]pyrimidine (5.35 g.), m.p. 178°-179°.
