Under a N2 atmosphere, 6-morpholino-2′,3′,5′,6′-tetrahydrospiro[indoline-3,4′-pyran] (0.19 g, 0.69 mmol) was dissolved in DMF (2.00 mL, 26 mmol) and sodium hydride (0.018 g, 0.76 mmol) was added and the reaction was treated with 4-chloro-7-fluoro-2-(2-fluorophenyl)-3-methylquinoline (0.100 g, 0.35 mmol) and heated to 140° C. for 6 h. The reaction was then diluted with EtOAc and washed with 2% sodium bicarbonate then brine. The layers were separated and the organic layer was dried (Na2SO4), filtered and concentrated in vacuo. The reaction was then purified by flash column chromatography eluting with 40% to 60% EtOAc in hexane and then purified by preparative reverse phase HPLC to afford 1-(7-fluoro-2-(2-fluorophenyl)-3-methyl-4-quinolinyl)-6-(4-morpholinyl)-1,2,2′,3′,5′,6′-hexahydrospiro[indole-3,4′-pyran].
