Following a procedure analogous to the procedure described in Intermediate 11 using methyl 2,6-difluoro-3-{[(2-propen-1-yloxy)carbonyl]amino}benzoate (80 g, 295 mmol) and 2-chloro-4-methylpyrimidine (41.6 g, 324 mmol) the title compound of Step E was obtained (65 g, 60.2% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 9.49-9.60 (m, 1H), 8.72-8.77 (m, 0.3H), 8.58-8.64 (m, 0.6H), 7.57-7.83 (m, 2H), 7.15-7.25 (m, 1H), 5.89-6.01 (m, 1H), 5.75-5.82 (m, 0.6H), 5.20-5.40 (m, 2H), 4.55-4.62 (m, 2H), m/z (ES+): 368 [M+H]+.
