実験手順

A mixture of 4-amino-2-methylthiopyrimidine (2.1 g.), 2,2,2-trifluoroethylisothiocyanate (2.8 g.) and acetonitrile (5 ml.) was stirred at 70° for 72 hours and then cooled, and the solid that crystallised was collected to give 4-[3-(2,2,2-trifluoroethyl)thioureido]-2-methylthiopyrimidine (2.15 g.) which was used without further purification.
