1-Amino-5-(4-methylbenzoyl)-4-(4-methylphenyi)pyrimidine-2(1H)-thione (1) react with the various isothiocyanates (2a-g) under different conditions to yield the new N, N'-disubstituted thioureas (3a-g). The structures of these compounds (3a-g) were determined by elemental analysis, IR, H-1 and C-13 NMR spectroscopic measurements.
