Ethyl 2-(7-((3-chlorobenzyl)oxy)-2-oxo-1,2,3,4-tetrahydroquinolin-3-yl)acetate (Example 51, product from Step D, 200 mg, 0.54 mmol) was dissolved in a 7 N solution of ammonia in methanol (10 mL) and stirred at room temperature for 2 weeks. The resulting precipitate was collected by filtration, washed with methanol (3 mL) and was dried under vacuum to give the title compound as a white solid (111 mg, 60%). 1H NMR (400 MHz, DMSO-d6) δ 10.08 (s, 1H), 7.53-7.33 (m, 5H), 7.06 (d, J=8.3 Hz, 1H), 6.85 (br s, 1H), 6.57 (dd, J=2.4, 8.3 Hz, 1H), 6.51 (d, J=2.4 Hz, 1H), 5.05 (s, 2H), 2.93-2.70 (m, 2H), 2.71-2.54 (m, 2H), 2.11 (dd, J=8.5, 15.2 Hz, 1H). [M+H]=345.1.
