실험 절차

To a solution of Example 437C (10.4 g, 56.1 mmol) in toluene (112 mL) was added 2-fluoronitrobenzene (6.0 ml, 56 mmol) and CsF (852 mg, 5.6 mmol). The reaction mixture was stirred under reflux conditions for 18 hours, and allowed to cool to ambient temperature. The mixture was diluted with ethyl acetate (100 ml), washed with 10% HCl (2×50 ml), followed by brine (3×100 ml), then dried (Na2SO4) and evaporated in vacuo to obtain the title compound (16.5 g, 94%). MS (ESI) m/e 367 (M+H)+.
