[5-(6-Hydroxynaphthalen-2-yl)-2,2-dimethyl-1,3-dioxinan-5-yl]-carbamic acid tert-butyl ester (Example 13, 498 mg, 0.00133 mol, Apex), PS-triphenylphosphine (3.00 mmol/g loading, 689 mg, 0.00207 mol, Aldrich) were slurried in Tetrahydrofuran (10 mL, Acros), then trans-4-butylcyclohexanol (0.255 g, 0.00163 mol, Synthon) and diisopropyl azodicarboxylate (0.315 mL, 0.00160 mol, Acros) was added. The reaction was stirred at room temperature. After 4 d, the mixture was diluted with ethyl acetate, filtered and concentrated and the crude product was taken up into methylene chloride and subjected to silica gel chromatography purification to give the title compound in 353 mg yield (52%).
