Procedure

To a solution of [7-[(4-oxo-1H-quinolin-3-yl)carbonylamino]tetralin-1-yl]aminoformic acid tert-butyl ester (273) (250 mg, 0.6 mmol) in dichloromethane (2 mL) was added TFA (2 mL). The reaction was stirred at room temperature for 30 min. More dichloromethane (10 mL) was added to the reaction mixture and the solution was washed with sat. NaHCO3 solution (5 mL). A precipitate began to form in the organic layer so the combined organic layers were concentrated to yield N-(1-aminotetralin-7-yl)-4-oxo-1H-quinoline-3-carboxamide (273-I) (185 mg, 93%). HPLC ret. time 1.94 min, 10-99% CH3CN, 5 min run; ESI-MS 334.5 m/z (MH+).
