Procedure

To a solution of ethyl 7-[(3-chlorophenyl)methoxy]quinoline-3-carboxylate (Example 3, 150 mg, 0.44 mmol) in MeOH (0.7 mL) and THF (1.7 mL) was added LiOH (13 mg, 0.54 mmol) in H2O (1.7 mL). The reaction was stirred for 14 h at ambient temperature. The crude reaction mixture was concentrated to dryness under reduced pressure. 10% HCl (aq.) (6.0 mL) was added, and the precipitate was collected and dried under high pressure to afford the title compound as a white solid (106 mg, 77%). 1H NMR (400 MHz, DMSO-d6) δ 9.25 (d, J=2.3 Hz, 1H), 8.79 (d, J=2.3 Hz, 1H), 8.25 (s, 1H), 8.03 (d, J=9.4 Hz, 1H), 7.63 (s, 1H), 7.58-7.41 (m, 4H), 5.37 (s, 2H). [M+H]=314.2.
