N-(1(S)-benzyl-2-hydroxyethyl)-3(R)-(3-(biphenyl-4-yI)-1H-pyrrol-1-yl)succinamic acid benzyl ester → N-(1(S)-benzyl-2-hydroxyethyl)-3(R)-(3-(biphenyl-4-yl)-1H-pyrrol-yl)succinamic acid

Participants

Reaction Steps

A suspension of 10% Pd/C (wet DeGussa type, 15 mg) and N-(1(S)-benzyl-2-hydroxyethyl)-3 (R)-[3-(biphenyl-4-yl)-1H-pyrrol-1-yl]succinamic acid benzyl ester (68 mg, 0.12 mmol) in EtOAc (5 mL) was stirred under H2 for 20 hours. The catalyst was filtered onto Celite and rinsed with MeOH. The filtrate was concentrated under reduced pressure to give a yellow oil, which was purified via flash column chromatography with a 1% HOAc/2-5% MeOH/CH2Cl2 stepwise gradient elution to provide 47 mg (82%) of N-(1(S)-benzyl-2-hydroxyethyl)-3(R)-[3-(biphenyl-4-yl)-1H-pyrrol-1-yl]succinamic acid as a white solid.
