A solution of 2.14 g. of 4-dimethylaminopiperidine and 4.0 g. of 9-acetoxyxanthene in 100 ml. of sieve dried benzene was refluxed for 24 hours. The mixture was then washed with a 5 percent aqueous solution of sodium carbonate, dried and the solvent removed in vacuo. The residue was recrystallized three times from hexane to afford 1-(9-xanthenyl)-4-dimethylaminopiperidine, m.p. 92°-93°C.
