A solution of 3.5 g. (14.6 mmoles) of 9-acetoxyxanthene and 2.1 g. (14.8 mmoles) of 2-(dimethylaminomethyl)-piperidine in 50 ml. of toluene was refluxed for 40 hours. The mixture was then washed with sodium bicarbonate, dried and evaporated. Recrystallization of the residue from hexane afforded 1-(9-xanthenyl)-2-(dimethylaminomethyl)-piperidine, m.p. 81°-83°C.
