实验步骤: 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. was heated overnight at 80°-90° C. evaporated The residual gum was dissolved in dichloromethane washed with water dried filtered evaporated

实验步骤: A 6 g portion of 2-chloromethyl-1,4-bis(phenylmethyl)piperazine was dissolved in 20 ml of dioxane. To this was added 3.14 g of potassium carbonate and 68 ml of 40% aqueous dimethylamine. The mixture was stirred in a sealed pressure bottle at 80° C. for 18 hours and then taken to dryness in vacuo. The gummy residue was mixed with water and dichloromethane. The aqueous layer was washed twice with dichloromethane. The organic solutions were combined, dried, filtered and evaporated, giving 6.23 g of 2-dimethylaminomethyl-1,4-bis(phenylmethyl)piperazine as a gum. The aqueous layer was washed twice with dichloromethane dried filtered evaporated
