Reaction Steps

9.7 g (61.2 mmol) of N-methyl-N′-(3-hydroxypropyl)piperazine dissolved in 10 ml of acetonitrile are added dropwise to a solution of 100 ml of acetonitrile and 40 ml of 4 N HCl in dioxane and cooled using a water bath that the internal temperature did not exceed 40° C. 8 ml (66.3 mmol) of trichloromethyl chloroformate in 10 ml of acetonitrile are subsequently added dropwise with ice-cooling at an internal temperature of 2-10° C., and the mixture is subsequently stirred at room temperature for 15 h. The precipitate formed is filtered off with suction, washed with acetonitrile, and the residue is dried in vacuo.
