실험 절차

3,4,5-Tris(octadecyloxy)cyclohexylmethyl alcohol (238 mg, 0.26 mmol), 4-hydroxy-2-methoxybenzaldehyde (79 mg, 0.52 mmol) and triphenylphosphine (149 mg, 0.57 mmol) were dissolved in THF (6 ml), diisopropyl azodicarboxylate (115 mg, 0.57 mmol) was added, and the mixture was stirred for 5.5 hr. Water (1 ml) was added to the reaction mixture and the mixture was concentrated. The residue was precipitated with acetonitrile (2.5 ml) to give 2-methoxy-4-[3′,4′,5′-tris(octadecyloxy)cyclohexylmethyloxy]benzaldehyde (272 mg, 0.26 mmol, 100%).
