Participants

Reaction Steps

A solution of 6-(4-aminophenyl)-5-methyl-4,5-dihydro-1,2,4-triazin-3(2H)-one (3 g) and phenyl isothiocyanate (1.8 ml) in dimethylformamide (30 ml) was stirred at room temperature for 6 hours and then concentrated under reduced pressure. To the residue was added water and the thus-produced crystals were recovered by filtration, washed with water and dried to give 6-[4-(3-phenyl-thioureido)phenyl]-5-methyl-4,5-dihydro-1,2,4-triazin-3(2H)-one (5.32 g).
