Procedure

Catalytic hydrogenation of 10.17 g (26.04 mmol) of (E,E)-3,3'-[4-[[5-(acetyloxy)pentyl]oxy]-1,3-phenylene]bis-2-propenoic acid dimethyl ester from the preceding example was carried out using 2.03 g of 10% palladium on carbon, in 125 mL of dry tetrahydrofuran, at room temperature and 1 atmosphere. After filtration of the catalyst and concentration of the filtrate, the title compound was obtained in quantitative yield, as a pale-yellow oil.
