A magnetically stirred solution of amine 5 (10.0 g, 103 mmol) inTHF (250 mL) was treated with potassium tert-butoxide (23.0 g,205 mmol) at 0 C. The resultant suspension was brought to roomtemperature and stirred for 1 h before the dropwise addition of ofluoronitrobenzene(12 mL, 113 mmol). The reaction mixture wasstirred for 3 h, quenched with water (300 mL) and extracted withEtOAc (3 150 mL). The combined organic extracts were dried(MgSO4), filtered and concentrated under reduced pressure. Thecrude oil was purified by flash column chromatography (silica, 3:5v\/v EtOAc:hexanes) and concentration of the relevant fractions(Rf 0.42 in 1:1 v\/v EtOAc:hexanes) afforded the title compound(16.9 g, 77percent) as yellow crystals.1H NMR (300 MHz, Chloroform-d): d 9.11 (s, 1H, NH), 8.25 (d,J 8.1 Hz, 1H), 7.56e7.54 (m, 1H), 7.52e7.38 (m, 1H), 6.96e6.84 (m,1H), 6.78e6.74 (m, 1H), 6.20 (d, J 2.5 Hz, 1H), 3.76 (s, 3H). 13C NMR(75 MHz, Chloroform-d): d 142.7, 139.0, 136.8, 136.3, 133.4, 126.6,118.7, 115.8, 101.8, 35.2.
