Reaction Steps

N-3,3-Diphenylpropylpiperazine in the amount of 2.8 g (0.01 mole), 2.17 g (0.01 mole) of 3,4,5-trimethoxybenzyl chloride, 0.51 g (0.005 mole) of triethylamine, and 1.4 g (0.01 mole) of potassium carbonate were mixed with 20 ml of toluene, and the resulting mixture was heated at the refluxing temperature for 2 hours. The reaction liquid was left to cool, washed by shaking with water, and then the organic liquid layer was concentrated under reduced pressure to obtain 3.8 g (82.5% yield) of oily 1-(3,3-diphenylpropyl)-4-(3,4,5-trimethoxybenzyl)piperazine.
