Procedure

Finely ground sodium azide (325 mg., 5 mmole) is added to a solution of 7 -acetoxy-6-(2-cyanoethyl)-9-(5-phenyl-2-pentyloxy)-2,3,4,4a,5,6-hexahydro-1H-pyrido[1,2-a]quinoline (506 mg., 1 mmole) in 5 ml. of ethanol-free chloroform containing 271 mg. (2 mmole) N-methylpiperidine hydrochloride and 5 drops of N-methylpiperidine. The mixture is heated at reflux for one hour, another 2 mmole of N-methylpiperidine hydrochloride is added, refluxing continued for another hour and allowed to stand overnight at room temperature. The mixture is partitioned between chloroform and aqueous sodium carbonate solution. The aqueous layer is adjusted to pH 5, extracted again with chloroform and the combined organic layers washed with water and the chloroform is dried (MgSO4). Evaporation of solvent under reduced pressure affords the title compound.
