실험 절차

5-chloro-6-cyclopropylpyridin-3-ol (250 mg, 1.47 mmol), 3-bromo-4-fluorobenzonitrile (Preparation 37, 295 mg, 1.47 mmol) and potassium carbonate (611 mg, 4.42 mmol) were suspended in dimethylsulfoxide (6 mL). The reaction mixture was stirred at 5 hours at 50° C. then water (60 mL) was added and the suspension was extracted by ethyl acetate (3×30 mL). The organic layers were combined, washed with brine (3×15 mL), dried over magnesium sulfate, filtered and concentrated under vacuum to afford the title compound as a clear oil which solidified on standing (485 mg, 94%).
