Procedure

A mixture of [3-[(4-oxo-1H-quinolin-3-yl)carbonylamino]-4-tert-butyl-phenyl]aminoformic acid tert-butyl ester (353) (33 mg, 0.08 mmol), TFA (1 mL) and CH2Cl2 (1 mL) was stirred at room temperature overnight. The solution was concentrated and the residue was dissolved in DMSO (1 mL) and purified by HPLC (10-99% CH3CN/H2O) to yield the product, N-(5-amino-2-tert-butyl-phenyl)-4-oxo-1H-quinoline-3-carboxamide (260) (15 mg, 56%). 1H NMR (400 MHz, DMSO-d6) δ 13.23 (d, J=6.6 Hz, 1H), 12.20 (s, 1H), 10.22 (br s, 2H), 8.88 (d, J=6.8 Hz, 1H), 8.34 (d, J=7.8 Hz, 1H), 7.86-7.80 (m, 3H), 7.56-7.52 (m, 2H), 7.15 (dd, J=8.5, 2.4 Hz, 1H), 1.46 (s, 9H); HPLC ret. time 2.33 min, 10-99% CH3CN, 5 min run; ESI-MS 336.3 m/z (MH+).
