Reaction Steps

A flask charged with 8-bromo-N-(2,4-di-tert-butyl-5-hydroxyphenyl)-5-nitro-4-oxo-1,4-dihydroquinoline-3-carboxamide (430 mg, 0.83 mmol)) and Pd/C (60 mg, 0.56 mmol) was evacuated under vacuum, followed by purging with N2. EtOAc (4 mL) and HCl (1 mL of 1 M, 1.000 mmol) were added followed by evacuating under vacuum. The reaction was stirred overnight under an atmosphere of hydrogen, filtered through a plug of celite and concentrated to get 5-amino-N-(2,4-ditert-butyl-5-hydroxy-phenyl)-4-oxo-1H-quinoline-3-carboxamide (164 mg, 48%). LC/MS: m/z 408.5 (M+H)+ at 1.98 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
