Reaction Steps
A solution of ethyl 1-cyclopropyl-8-(4-amino-2-chloro-5-methyl-phenyl)-9-methyl-4-oxo-4H-quinolizine-3-carboxylate (70 mg, 0.171 mmol) in THF (6 mL) and water (2 mL) was treated with LiOH (29 mg, 0.690 mmol). The reaction was heated to 60° C. overnight and acidified with 1N HCl to pH 4. The precipitate was dissolved with ethyl acetate (50 mL) and washed with brine (2×20 mL). The organic phase was separated, dried, and concentrated. The precipitate was filtered to afford the title compound EXAMPLE 30 as yellow solid (51 mg, 78%). ESI-MS m/z: 383 (M+H)+; 1H NMR (300 MHz, DMSO-d6) δ ppm: 9.28 (d, J=7.5 Hz, 1H), 8.24 (s, 1H), 7.43 (d, J=7.5 Hz, 1H), 6.99 (s, 1H), 6.81 (s, 1H), 5.55 (s, 2H), 2.75 (s, 3H), 2.54-2.52 (m, 1H), 2.07 (s, 3H), 1.03-1.01 (m, 2H), 0.74-0.70 (m, 2H).
