Procedure

A mixture of 4-amino-2-(2-phthalimidoethylthio)pyrimidine (0.8 g.), 2,2,2-trifluoroethylisothiocyanate (0.56 g.) and dimethyl formamide (2 ml.) was stirred at 70° for 72 hours. The mixture was cooled, diluted with acetonitrile and filtered to give 4-[3-(2,2,2-trifluoroethyl)thioureido]-2-(2-phthalimidoethylthio)pyrimidine (0.7 g.), m.p. 238°-241°.
