Hydrochloric Acid → HCID 13649260, compound

Participants

Reaction Steps

1.73 g of (2S)-N-(α,α-dimethylbenzyl)-2-benzoylamino-6-(benzyloxycarbonylamino)hexanamide (prepared as described in Example 8) dissolved in 80 ml of ethanol and 4 ml of 1N hydrochloric acid was catalytically reduced by hydrogen gas in the presence of 0.33 g of 10% w/w palladium-on-carbon at room temperature. After filtering off the catalyst, the filtrate was concentrated by evaporation under reduced pressure to afford 1.35 g of the title compound as an amorphous substance melting at 94°-101° C. (with decomposition)
