Procedure

The mixture of spiro[4.5]decan-8-ol (0.915 g, 0.00593 mol), 6-hydroxy-naphthalene-2-carboxylic acid methyl ester (1.00 g, 0.00494 mol) and triphenylphosphine (1.56 g, 0.00593 mol) in toluene (10 mL, 0.1 mol) was heated to reflux, and diisopropyl azodicarboxylate (1.17 mL, 0.00593 mol) was added dropwise and was stirred and refluxed for 6 hours. The mixture was taken up into DCM and subjected to chromatography purification with EtOAc/hexane (0:100 to 40:60) to give product as a white solid (1.02 g, 61%). LCMS Rt=2.58 min, m/z=339.34, (M+1, 100%).
