実験手順
A suspension of 10 g of 2-cyanoamino-4,6-dimethylpyrimidine in 50 ml of pyridine was saturated with hydrogen sulfide and stored for 1 hour at 25°. The H2S treatment was repeated twice more, and the mixture was allowed to stir at 25° for 16 hours. Methylene chloride was added, and the product was filtered and washed with methylene chloride to afford 8 g of 4,6-dimethylpyrimidin-2-yl thiourea, m.p. >260°. IR (Nujol) 3280, 3180, 3120, 1610 cm-1.
