Reaction Steps
Under a N2 atmosphere, 6-morpholino-2′,3′,5′,6′-tetrahydrospiro[indoline-3,4′-pyran] (0.18 g, 0.65 mmol) was dissolved in DMF (2.00 mL, 26 mmol) and sodium hydride (0.017 g, 0.72 mmol) was added. The reaction was allowed to stir for 15 minutes at rt. 4,7-Dichloro-2-(2-fluorophenyl)-3-methylquinoline (0.100 g, 0.33 mmol) was added and the reaction was heated to 140° C. for 5 h. The reaction was diluted with EtOAc and washed with 2% sodium bicarbonate then brine. The organic layer was dried (Na2SO4), filtered, and concentrated in vacuo. The crude solid was purified by flash column chromatography eluting with 40% to 60% EtOAc in hexane, followed by further purification by preparative reverse phase HPLC to afford 1-(7-chloro-2-(2-fluorophenyl)-3-methyl-4-quinolinyl)-6-(4-morpholinyl)-1,2,2′,3′,5′,6′-hexahydrospiro[indole-3,4′-pyran].
