Reaction Conditions

Temperature130 °C

Reaction Steps

5.6 g of acid maleate of 2-(1-piperazinyl)pyrimidine are dissolved in 80 ml of dimethylformamide, then 5.6 ml of triethylamine and 3.8 g of 3,4-methylenedioxy benzoyl chloride are added. The mixture is heated for 12 hours at 130° C. then the solvent is evaporated to dryness in vacuo. The residue is taken up in a dilute solution of hydrochloric acid and washed with ether. The aqueous phase is rendered alkaline by a sodium carbonate solution and extracted with ethyl acetate. The solution is dried over sodium sulfate and the solvent is evaporated to dryness.
