Cyclohexyl isothiocyanate → 1-{3-[4-(4-Chlorobenzyl)piperazin-1-yl]propyl}-3-cyclohexylthiourea

Participants

Reaction Steps

1-(3-Aminopropyl)-4-(4-chlorobenzyl)piperazine (5.36 g; 20 mmole) was reacted with cyclohexyl isothiocyanate (2.82 g; 20 mmole) in methylene chloride (35 ml) for two hours in the manner described in Example 17. The crude product was isolated and chromatographed on silica gel in analogous manner. The product, on recrystallization from ethanol, yielded the title compound (2.98 g; 36% yield) as colorless crystals, m.p. 127°-128° C.
