Procedure

To a stirred solution of 3-chloro-N-[4-(3-chloro-4-fluoroanilino)-3-cyano-7-(4-morpholinyl)-6-quinolinyl]propanamide (0.30 g, 0.61 mmol) in 1.2 ml of THF at 0° was added 1.2 ml of 1.0 M KOtBu/tBuOH dropwise during 1 m. After 2 h at 0° the reaction was quenched with solid CO2 and partitioned with DCM-water. The organic layer was washed with water, dried, and evaporated to give 0.28 g of the title compound as a white amorphous solid; ms 452.2 (M+H)+.
