A mixture of 4-chlorobenzhydryl chloride (5.32 g, 22.4 mmol), isopropanol (80 ml) and sodium iodide (3.41 g, 22.8 mmol) was stirred at room temperature for 30 minutes. Thereto was added homopiperazine (11.2 g, 112 mmol), and the mixture was stirred at 95° C. for 18 hours. The solvent was distilled off, and the concentrate was poured into a saturated aqueous solution of sodium hydrogencarbonate and extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate and evaporated. The thus-obtained crude product was used for the next reaction without purification.
