Versuchsvorschrift

In a round-bottomed flask equipped with a mechanical stirrer, 50 g of 4-(3-trifluoromethylphenyl)-4-piperidinol are charged to 377 ml of water and 514 ml of concentrated hydrochloric acid. The mixture is left to react at reflux for 5 hours and is then cooled to ambient temperature. A white solid precipitates. It is filtered off through a Büchner funnel and dried in an oven. 37 g of a white solid are isolated. M.p. 203-204° C.
