Versuchsvorschrift

To the solution of t-butyl carbonazidate in diethyl ether, 49.6 g (0.189 mol) of triphenylphosphine was added in small portions under cooling with ice, and the reaction solution was stirred at room temperature for 1 hour, and the precipitated solid was collected by filtration, washed with 200 mL of hexane and dried under reduced pressure to give 67 g of the desired product as white crystals.
