Trifluoroacetic acid → (6S,7S)-5-methyl-6-[({4-[(2-methylquinolin-4-yl)methoxy]phenyl}amino)carbonyl]-5-azaspiro[2.5]octane-7-carboxylic acid

Participants

Reaction Steps

TFA (1.0 mL) was added to a solution of tert-butyl(6S,7S)-5-methyl-6-[({4-[(2-methylquinolin-4-yl)methoxy]phenyl}amino)carbonyl]-5-azaspiro[2.5]octane-7-carboxylate (105.0 mg) in CH2Cl2 (1.0 mL) and the mixture was stirred at room temperature for 5 h. The solvent was removed to provide (6S,7S)-5-methyl-6-[({4-[(2-methylquinolin-4-yl)methoxy]phenyl}amino)carbonyl]-5-azaspiro[2.5]octane-7-carboxylic acid (140 mg) as an TFA salt. ESI (M+H)+460.3.
