1.4 G. of sodium azide (NaN3) in 6 ml. of water was added to a solution of 3.6 g. of 1-methyl-4-phenyl-3,4-epoxypiperidine in 20 ml. of dioxane and the resulting combined solution refluxed for two hours. A further portion of 1.4 g. of NaN3 in 6 ml. of water was then added and the reaction mixture refluxed overnight. Upon cooling 3.2 g. of crystals of the dresired 1-methyl-4-phenyl-4-azido-3-hydroxypiperidine were obtained, which had a melting point of 170°-71° C.
