Reaction Steps
A mixture of 4-(4-chloro-6-methoxyquinolin-2-yl)benzonitrile (Seem Example 11, step 1) (1 g, 3.4 mmol), CsF (5.2 g, 34 mmol), and n-Bu4NBr (109 mg, 0.34 mmol) in DMSO (10 mL) was heated to 150° C. for 2 h. An aqueous/EtOAC workup was followed by purification by column chromatography (PE/EA=10/1) to afford desired product (300 mg, 31.7%).
