1-Nitro-3-(1-azidoethyl)benzene (1.3 g, 6.76 mmol) was dissolved in tetrahydrofuran and triphenylphosphine (1.9 g, 7.4 mmol) was added. The resulting solution was stirred at ambient temperature for 18 hours. 1M aqueous sodium hydroxide (1 ml) was then added and the stirring continued for 48 hours. The reaction was diluted with ethyl acetate, washed with brine several times, dried over magnesium sulfate, filtered, and evaporated. The residue was chromatographed (silica gel, 2:1 hexane:ethyl acetate) to provide 1.1 g of the title compound. (99%). 1H NMR(CDCl3)
