Procedure

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 (35 mg, 0.057 mmol) in 2 M HCl (2 mL) and methanol (2 mL) was heated at reflux for 3 h. The solution was concentrated, diluted with aqueous acetic acid and purified by HPLC to give N-[2-chloro-4-[[[(1H-indazol-4-yl)methyl]amino]carbonyl]benzoyl]-3-(thiophene-2-carbonyl)amino-L-alanine (8 mg, 26%) along with N-[2-chloro-4-[[[(1H-indazol-4-yl)methyl]amino]carbonyl]benzoyl]-3-(thiophene-2-carbonyl)amino-L-alanine, methyl ester (13 mg, 42%).
