Procedure
5 g of piperazinoacetic acid morpholide and 4.2 g of chlorobenzoyl chloride are brought together in 50 ml of methylene chloride at 0° C. The mixture is stirred at room temperature for 2 hours and cooled again to 0° C., whereupon a precipitate separates out, and is recrystallised from isopropanol.
