EXAMPLE 8 4-Amino-2-methyl-5-pyrimidinecarbothioamide Hydrogen sulfide is passed through a mixture of 4-amino-2-methyl-5-pyrimidinecarbonitrile (6.707 g., 0.050 m.), triethylamine (7.0 ml., 0.050 m.), dimethylformamide (25 ml.) and pyridine (100 ml.) with stirring for 3 hours at ambient temperature. The mixture is poured into ice water (500 ml.) and the cream-colored solid which separates is collected by filtration, washed with water, dried at 110 C./0.1 mm. The yield of product melting at 260 C. dec. (uncorr.) is 7.663 g. (91.1%). This material is recrystallized from dimethylformamide-water (Darco G-60) affording colorless crystals melting at 264 C. dec. (uncorr.) in a yield of 5.110 g. (60.8%). Analysis for: C6 H8 N4 S; Calculated: C, 42.83; H, 4.79; N, 33.32; S, 19.06; Found: C, 42.79; H, 4.83; N, 33.34; S, 19.19.
