Di-tert-butyl azodicarboxylate was added at 0° C. to a mixture of 1,3-cyclopentandiol (1.02 g), 5-fluoro-2-nitrophenol (0.79 g) and triphenylphosphine (1.97 g) in THF (15.0 ml). After stirring at room temperature over weekend the mixture was treated with 2 M aq. HCl (20.0 ml) and refluxed for 30 min. The reaction mixture was diluted with methylene chloride. The layers were separated. The organic layer was passed through a hydrophobic frit and concentrated in vacuo. The crude was purified by chromatography to yield the desired product.
