Participants

Reaction Steps

(2-oxo-1-phenylpiperidin-4yl)methyl methanesulfonate (0.37 g, 1.3 mmol) was dissolved in dimethylsulfoxide (6 mL), treated with sodium azide (0.18 g, 2.8 mmol, 2.1 equiv) and placed into a preheated oil bath at 60° C. for 18 hours. The mixture was cooled to ambient temperature, diluted with ethyl acetate (50 mL) and washed twice with water (50 mL) and brine (50 mL).
