Versuchsvorschrift

16.49 kg of 4-{3-[cis-hexahydrocyclopenta[c]pyrrol-2(1H)-yl]propoxy}benzamide, 16.36 kg of acetone, 6.76 kg of concentrated aqueous hydrochloric acid and 18.96 kg of water are introduced into a reactor. The mixture is stirred and heated at 50° C. for 1 hour. The mixture is then filtered in the hot state into a second reactor containing 57.67 kg of acetone and 1.65 kg of water. The mixture is then brought to reflux and 73.32 kg of acetone are added. Reflux is maintained for 10 minutes and then cooling to 0° C. is carried out. The product is filtered off and the solid obtained is washed with acetone. The product is obtained in the form of a powder in a yield of 85% and with a chemical purity greater than 99%.
