Procedure

Methyl 3,4,5-trihydroxybenzoate (200 mg, 1.1 mmol), 2,5,8,11,14,17,20,23,26,29,32-undecaoxatetratriacontan-34-yl-4-methylbenzenesulfonate (2.58 g, 3.85 mmol), and 18-crown-6 (100 mg, 0.38 mmol) are transferred to a round bottom flask equipped with a Teflon-coated stirbar. Acetone (10 mL) is added and the flask is equipped with a reflux condenser. The mixture is refluxed with constant stirring overnight. The next day silica (4 g) is added and the solvent evaporated. After purification by column chromatography, a clear oil is obtained (887 mg, 48% yield).
