Reaction Steps
Dibenzyl N-[N-(3-hexadecanoyloxyoctadecanoyl)-L-threonyl]-L-glutamate (48 g) in demethylformamide (500 ml) was hydrogenated over palladium black (1 g) at room temperature at 1 atmospheric pressure. After the theoritical amount of hydrogen was adsorbed, dimethylformamide was removed under reduced pressure. The residual crude crystal was recrystallized from ethanol to give N-[N-(3-hexadecanoyloxyoctadecanoyl)-L-threonyl]-L-glutamic acid (35.5 g).
