Procedure
Intermediate I-2a was prepared from 2,3,4,6-tetrafluoronitrobenzene (25 g, 128 mol) and 2-fluoro-4-bromoaniline (24.36 g, 128 mol) using procedures analogous to those described above for the preparation of Intermediate (I-1a) to afford 25 g of the product (64% yield). H1NMR (DMSO-d6, 300 MHz): δ 8.84 (s, 1H), 7.70-7.60 (m, 1H), 7.56 (dd, 1H), 7.29 (d, 1H), 7.04 (t, 1H). LCMS: 99.02%, m/z=366.9 (M+2).
