実験手順

To a solution of 2-(methylthio)benzo[d]oxazol-6-ol (8.5 g, 46.7 mmol, 1 eq) in 80 mL of N,N-dimethylformamide was added 4-chloro-N-methylpyridine-2-carboxamide (16.0 g, 93.4 mmol, 2.0 eq) and cesium carbonate (45.7 g, 140.1 mmol, 3.0 eq). The reaction mixture was stirred at 75° C. for 6 hours. After the mixture was cooled to room temperature, the mixture was added 120 mL of water. After filtration, the solid was purified by silica gel column eluted with ethyl acetate and hexane to give the titled compound. MH+=316.
