実験手順

A mixture of 1-(6-hydroxy-naphthalen-2-ylmethyl)-piperidine-4-carboxylic acid ethyl ester (0.400 g, 1.28 mmol), 4-phenyl-cyclohexanol (0.2479 g, 1.406 mmol) and triphenylphosphine (0.6695 g, 2.553 mmol) in toluene (5 mL, 40 mmol) was stirred for 20 min, then diisopropyl azodicarboxylate (0.32 mL, 1.5 mmol) was added dropwise at 0° C. The solution was stirred at reflux overnight. The reaction was added silica gel and the solvent was concentrated. The residue was purified with silica gel eluted with EtOAc in hexanes from 0 to 20% to give product as an oil (0.3 g, 50%). LCMS: Rt=1.75 min, m/z=472.45 [M+H].
