Reaction Steps

A mixture of 1'-methyl-4-aminoxanthene-9-spiro-4'-piperidine (0.06 g.) and acetic anhydride (0.5 ml.) in ether (20 ml.) is stirred at room temperature for 0.5 hour. The ether solution is washed with saturated sodium carbonate solution and water, dried with MgSO4 and the ether evaporated to give a gummy residue. The residue is crystallised from hexane to give 1'-methyl-4-acetamidoxanthene-9-spiro-4'-piperidine, m.p. 176°-178° C.
