Participants

Reaction Steps

An aqueous solution of sodium hydroxide (1 M, 190 μL, 0.19 mmol) was added to a solution of N-[2-chloro-4-[[[[1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-4-yl]methyl]amino]carbonyl]benzoyl]-3-(thiophene-2-carbonyl)amino-L-alanine, methyl ester (108 mg, ˜0.169 mmol) in methanol (1 mL). The solution was allowed to stir at room temperature for 2 days, then it was concentrated and held under high vacuum for 1 h to give N-[2-chloro-4-[[[[1-(tetrahydro-2H-pyran-2-yl)-1H-indazol-4-yl]methyl]amino]carbonyl]benzoyl]-3-(thiophene-2-carbonyl)amino-L-alanine (100 mg, 97%) as a yellow solid.
