Reaction Steps

A solution of (3S)-3-[(2S)-5-benzyloxycarbonyl-2-(tertiarybutoxycarbonylamino)pentanoyl]oxyhexadecanamide (100 mg) in methanol (2 ml) was hydrogenated over 10% palladium on carbon (20 mg) under atmospheric pressure of hydrogen for 3.5 hours at room temperature. Then, the catalyst was filtered off with celite and the filtrate was concentrated under reduced pressure. The residue was recrystallized from a mixture of ethyl acetate (0.5 ml) and n-hexane (1 ml) to give (3S)-3-[(2S)-5-carboxy-2-(tertiarybutoxycarbonylamino)-pentanoyl]oxyhexadecanamide (40 mg).
