Reaction Steps

Benzyl 5-formyl-2(S)-phthalimidopentanoate (4.72 g) was dissolved in 230 ml of ethyl acetate and hydrogenated at 5 psig of hydrogen over 0.82 g of 10% palladium on carbon. After the uptake of 1 equivalent of hydrogen, catalyst was removed by filtration. Removal of solvent afforded 3.64 g of 5-formyl-2(S)-phthalimidopentanoic acid.
