Procedure

N-(2-Methoxy-5-methoxycarbonylphenyl) 3,4,5-tris(octadecyloxy)cyclohexylcarboxamide (225 mg, 0.21 mmol) was dissolved in dehydrated THF (2.5 ml), 1M DIBAL/toluene (0.6 ml, 0.6 eq) was added dropwise, and the mixture was stirred for 5 hr. After completion of the reaction, 1N hydrochloric acid was added to quench the reaction, and the mixture was extracted with chloroform (10 ml), and washed with 1N hydrochloric acid (5 ml). The solvent was evaporated and the residue was precipitated with methanol (15 ml) and slurry-washed with acetonitrile (10 ml) and 1N hydrochloric acid (10 ml) to give N-(5-hydroxymethyl-2-methoxyphenyl) 3,4,5-tris(octadecyloxy)cyclohexylcarboxamide (200 mg, 0.18 mmol, yield 86%).
