実験手順
Using multiple iterations of a procedure analogous to the procedure described in Intermediate 11 using methyl 2-fluoro-5-{[(2-propen-1-yloxy)carbonyl]amino}benzoate (104 g, 411 mmol) and 2-chloro-4-methylpyrimidine (59 g, 493 mmol), the title compound of Step B was obtained (100 g, 69.9% yield). 1H NMR (400 MHz, CDCl3) δ ppm 13.67-13.75 (br, 1H), 8.50-8.53 (m, 0.3H), 8.31-8.38 (m, 1H), 7.50-7.82 (m, 2.6H), 6.56-7.20 (m, 3.5H), 6.20-6.25 (m, 1H), 5.82-6.01 (1.3H), 5.20-5.40 (m, 2.6H), 4.50-4.61 (m, 2.6H), 4.31-4.41 (m, 0.9H).
