A suspension of 2.42 g of p-methoxyphenylthiono-phosphine sulfide and 1.79 g of benzo-1,2,3-thiadiazole-7-carboxamide in 95 ml of toluene is refluxed under a nitrogen atmosphere for 6 hours. The mixture is then evaporated in vacuon and the residue is suspended in ethyl acetate and filtered off. The filtrate is recrystallized from ethyl acetate/tetrahydrofuran with added active charcoal. 1.1 g of yellow crystals of melting point 129°-131° C. result.
