Sodium Hydroxide → N-(5-Amino-2-mercaptomethylpentanoyl)-L-tryptophane

Participants

Reaction Steps

To a solution of N-(2-acetylthiomethyl-5-aminopentanoyl)-L-tryptophane methyl ester trifluoroacetate (3 g) in methanol (60 ml) N sodium hydroxide (60 ml) is added. After 4 hours the solution is applied to a column of Dowex 50 ion exchange resin in the hydrogen cycle. After washing with water, the N-(5-amino-2-mercaptomethylpentanoyl)-L-tryptophane is eluted with pyridine-acetic acid buffer at pH 6.5.
