Benzyl O-(O-benzyl-N-benzyloxycarbonyl-L-serinyl)-N-trifluoroacetyl-L-serinate → O-(L-serinyl)-N-trifluoroacetyl-L-serine

Participants

Reaction Steps

A mixture of benzyl O-(O-benzyl-N-benzyloxycarbonyl-L-serinyl)-N-trifluoroacetyl-L-serinate (1 g) and 10% palladium on activated carbon (1 g) in acetic acid (30 ml) was hydrogenated under hydrogen at 40 psi at room temperature for 6 hours. The reaction mixture was filtered with Celite (filter aid, trade mark, made by Nakarai Chemicals) and the filtrate was concentrated in vacuo and the residue was diluted with water (50 ml) and lyophylized to give O-(L-serinyl)-N-trifluoroacetyl-L-serine (430 ml).
