Reaktionsschritte

A mixture of 4-(methylthio)benzyl chloride (28.6 g), 1-(2-hydroxyethyl)piperazine (21.6 g), triethylamine (16.8 g), and ethanol (250 ml) is stirred at room temperature for 5 hours. The ethanol is then removed in vacuo and water added to the residue. The product is extracted with ether, dried, and the ether evaporated to give 31.6 g of 1-(2-hydroxyethyl)-4-[4-(methylthio)benzyl] piperazine as an orange oil, suitable for use in the next reaction.
