Participants

Reaction Steps

A solution of 10.0 g (0.035 mole) 1-hydroxy-2,6-diphenyl-4-piperidone oxime, 22.0 g (0.22 moles) 1-hexanol and 7.0 g (0.073 moles) methanesulfonic acid in 250 mL tetrahydrofuran is heated at 60° C. for 12 hours. The solution is then washed three times with 10% aqueous sodium carbonate solution. The organic phase is dried over anhydrous sodium sulfate and concentrated. 3.2 g (20% yield) of the title compound is isolated as a clear oil after purification by LC (silica gel, ethyl acetate:hexane).
