Sodium Hydroxide → HCID 9850091, compound

Participants

Reaction Steps

An aqueous solution of sodium hydroxide (1 M; 0.305 Ml, 0.305 mmol) was added to a solution of N-[2,6-dichloro-4-[[[[3-[(thiophene-3-carbonyl)oxy]phenyl]methyl]amino]carbonyl]benzoyl]-3-[(thiophene-3-carbonyl)amino]-L-alanine, methyl ester (101 mg, 0.153 mmol) in methanol (2 Ml). The solution was allowed to stir overnight and then concentrated. An aqueous solution of sodium hydroxide (1 M; 0.210 Ml, 0.210 mmol) was added to a solution of N-[2,6-dichloro-4-[[[(3-hydroxyphenyl)methyl]amino]carbonyl]-benzoyl]-3-[(thiophene-3-carbonyl)amino]-L-alanine, methyl ester (58 mg, 0.105 mmol) in methanol (2 Ml). The solution was allowed to stir overnight and then concentrated. The residues from the two reactions were purified by HPLC and lyophilized to give N-[2,6-dichloro-4-[[[(3-hydroxyphenyl)methyl]amino]carbonyl]-benzoyl]-3-[(thiophene-3-carbonyl)amino]-L-alanine (107 mg, 78%) as a white solid.
