Trans-1-azidocyclopentan-2-ol 1.27 g was dissolved in DMF and treated with sodium hydride (400 mg. 60%) at room temperature for 1 h. 4-Fluoronitrobenzene (1.41 g) was added and the mixture stirred at 50° C. for 4 h and then left at room temperature overnight. The reaction was quenched with water and extracted with ether. The organic solution was washed with water, dried (MgSO4) and evaporated. Purification by flash chromatography (SiO2-20% DCM/hexane) gave trans-2-(4-nitrophenoxy)cyclopentylazide. 1H nmr (CDCl3) 8.22 (2H, d); 6.98 (2H, d); 5.63 (1H, m); 4.07 (1H, m); 2.20 (2H, m); 1.87 (4H, m).
