Reaction Steps
Prepared according to procedure L using 6-morpholino-2′,3′,5′,6′-tetrahydrospiro-[indoline-3,4′-pyran] (87 mg, 0.32 mmol) (described herein), 4.0M hydrochloric acid in 1,4-dioxane (66 μL, 0.25 mmol), 4-chloro-7-fluoro-2-(6-methoxypyridin-2-yl)-3-methylquinoline (80 mg, 0.25 mmol) (described herein), and NMP (440 μL), and heating in a microwave at 150° C. for 180 min. Purification afforded 6-(7-fluoro-3-methyl-4-(6-(4-morpholinyl)-2′,3′,5′,6′-tetrahydrospiro[indole-3,4′-pyran]-1(2H)-yl)-2-quinolinyl)-2-pyridinol as a yellow solid. 1H NMR (400 MHz, chloroform-d) δ ppm 7.65-7.85 (2H, m), 7.48-7.61 (1H, m), 7.27-7.32 (1H, m), 7.15 (1H, d, J=8.2 Hz), 6.78 (1H, d, J=6.7 Hz), 6.73 (1H, d, J=9.4 Hz), 6.37 (1H, dd, J=8.2, 2.3 Hz), 5.56 (1H, d, J=2.3 Hz), 3.98-4.09 (2H, m), 3.88-3.98 (2H, m), 3.62-3.78 (4H, m), 3.47-3.61 (2H, m), 2.84-3.03 (4H, m), 2.51 (3H, s), 2.09-2.24 (2H, m), 1.83-1.93 (1H, m), 1.71-1.83 (1H, m).
