Participants

Reaction Steps

0.74 g (7.17 mmol) of rhodium was added to a solution of 7.00 g (24.88 mmol) of (S)-2-tert-butoxycarbonylamino-3-(4-hydroxyphenyl)propionic acid in 50 ml of methanol, and hydrogenation was carried out at 50 C/6 bar pressure of hydrogen. After conversion was complete, the catalyst was filtered off and the filtrate was concentrated. The product was pure enough for further reactions.
