Reaction Steps
A mixture of 7.7 g of 2-chloromethyl-1,4-bis(phenylmethyl)piperazine, 12 g of N-methylpiperazine, 3.5 g of potassium carbonate, 150 ml of dioxane and 60 ml of water was heated overnight at 80°-90° C. and then evaporated. The residual gum was dissolved in dichloromethane, washed with water, dried, filtered and evaporated, giving 8.8 g of 2-[(N-methylpiperazinyl)methyl]-1,4-bis(phenylmethyl)piperazine.
