Following a procedure analogous to Intermediate 5, Step B using methyl 2-chloro-3-(2,6-difluorophenylsulfonamido)benzoate (31 g, 85.9 mmol) and 2-chloro-4-methylpyrimidine (12.2 g, 94.5 mmol) the title compound was obtained (33 g, 73.5% yield). 1H NMR (400 MHz, CDCl3) δ ppm 13.47-13.52 (br, 0.96H), 8.50-8.56 (m, 0.13H), 8.38 (d, J=5.3 Hz, 1H), 7.78-7.82 (m, 0.15H), 7.62-7.73 (m, 2H), 7.40-7.50 (m, 1.18H), 7.17-7.30 (m, 1.77H), 6.90-6.97 (m, 2.29H), 6.83 (d, J=5.3 Hz, 1H), 5.65 (s, 1H), 4.28 (s, 0.26H). MS (ES+): 458 [M+H]+.
