Procedure

A mixture of 7-[(4-oxo-1H-quinolin-3-yl)carbonylamino]-1,2,3,4-tetrahydroquinoline-1-carboxylic acid tert-butyl ester (183) (23 mg, 0.05 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, 4-oxo-N-(1,2,3,4-tetrahydroquinolin-7-yl)-1H-quinoline-3-carboxamide (299) (7 mg, 32%). HPLC ret. time 2.18 min, 10-99% CH3CN, 5 min run; ESI-MS 320.3 m/z (MH+).
