Versuchsvorschrift
A mixture of 16.1 g of 6-amino-4-chloro-1,2-dihydro-2-imino-1-pyrimidinol, 32.1 g of thiomorphline, and 75 ml of dimethyl formamide is heated at 110°C in a nitrogen atmosphere for 17 hours. The solvent is removed under high vacuum. The residue is dissolved in 2 normal hydrochloric acid, and the resulting solution made basic with 5% ammonium hydroxide. There is deposited 13.0 g (57%) of a crystalline solid mp 242°(dec). Recrystallization from methanol-ethanol gives an off-white crystalline solid, mp 246°C(dec).
