Versuchsvorschrift
A mixture of 4-amino-2-(4-phthalimidobut-2-ynylthio)pyrimidine (1.2 g.), 2,2,2-trifluoroethylisothiocyanate (0.85 g.) and DMF (10 ml.) was stirred at 70° for 72 hours. The mixture was evaporated to dryness, and the residue stirred with N aqueous HCl and then filtered to give 4-[3-(2,2,2-trifluoroethyl)thioureido]-2-(4-phthalimidobut-2-ynylthio)pyrimidine (0.4 g.), m.p. 124°-127°.
