Versuchsvorschrift

A mixture of 10 g. of ethyl p-[(3-phenylpropyl)amino]benzoate (prepared as described in Example 26), 10 g. of KOH and 200 ml. of ethanol-water (9:1) is refluxed for 4 hours. The mixture is acidified while hot with concentrated hydrochloric acid, diluted with water, cooled and filtered to give off-white crystals. Recrystallization from ethanol gives off-white crystals, m.p. 162°-163° C.
