Following a procedure analogous to the procedure described in Intermediate 5, Step B using methyl 3-(2,5-difluorophenylsulfonamido)benzoate (20.5 g, 62.7 mmol) and 2-chloro-4-methylpyrimidine (8.8 g, 68.9 mmol) the title compound was obtained (22.6 g, 85.3% yield). 1H NMR (400 MHz, CDCl3) δ ppm 13.40-13.50 (br s), 10.95-11.12 (br s), 8.72-8.80 (m), 8.57-8.63 (m), 7.77-7.82 (m), 7.36-7.72 (m), 7.22-7.30 (m), 6.43 (s), 4.52 (s); m/z (ES+): 424 [M+H]+.
