A solution of 1-[[3-(2-oxiranylethoxy]phenyl]methyl]piperidine (17 g), sodium azide (5.1 g) and ammonium chloride 2.73 g) in 25% aqueous ethanol (200 ml) was refluxed for 6 h and concentrated to ca. 130 ml. The concentrate was diluted with water (50 ml), saturated with potassium carbonate and extracted with isopropanol. The extract was dried and evaporated to give an oil (20 g) which was chromatographed on silica using dichloromethane:ethanol:ammonia (200:8:1) to give the title compound (10.5 g) as a colourless oil.
