実験手順

A mixture of 3.55 g of 3-nitro-5-(octadecyloxy)benzoic acid methyl ester and 0.75 g of 10% palladium on carbon in 100 ml of THF was shaken under an initial hydrogen pressure of 52 psi until uptake ceased after 1.5 hours. The catalyst was removed by filtration and the filtrate was concentrated at reduced pressure to give 3.28 g of pure 3-amino-5-(octadecyloxy)benzoic acid methyl ester.
