Participants

Reaction Steps

The aniline salt of (1R)-1-[(N-benzyloxycarbonyl-sarcosyl-L-tyrosyl-L-alanyl)amino]-ethylphosphonic acid was suspended in acetic acid and 10% palladium-on-carbon was added under argon. Acetic acid was then added. The mixture was stirred overnight at room temperature and then hydrogenated until the uptake of hydrogen ceased. The catalyst was filtered off and the filtrate was evaporated. The residual solid was triturated with methanol, filtered off, washed and dried. The solid was purified by reprecipitation from aqueous hydrochloric acid/ethanol with propylene oxide to give (1R)-1-(N-sarcosyl-L-tyrosyl-L-alanylamino)-ethylphosphonic acid of melting point 275°-277° C. (decomposition).
