After a suspension of 631 mg (1.54 mmol) of 1-[[[4-(4-propylpiperazin-1-yl)phenyl]carbonyl]amino]cyclohexanecarboxylic acid hydrochloride in 18 ml of acetic anhydride was stirred at 100° C. for 1 hour, the reaction solution was concentrated under reduced pressure. Toluene was added to the obtained residue, it was distilled off under reduced pressure three times, and acetic anhydride was removed by azeotropic distillation to obtain 500 mg (83%) of the title compound.
