Participants

Reaction Steps

A mixture of 4-(3,4-dichlorophenyl)-1-piperazineethanamine (0.01 mol) and 4-methyl-1-isothiocyanatobenzene (0.01 mol) in tetrahydrofuran (300 ml) was stirred at room temperature for 1 hour. The solvent was evaporated. The residue was recrystallized from DIPE. The precipitate was filtered off and dried. The product was used without further purification, yielding 4.2 g N-(4-methylphenyl)-N′-[2-[4-(3,4-dichlorophenyl)-1-piperazinyl]ethyl]thiourea (interm. 6).
