Reaction Steps
To a solution of methyl 2,6-difluoro-3-nitrobenzoate (25 g, 115 mmol) in MeOH (150 mL) was added 5% palladium on carbon (2.5 g). The mixture was stirred under H2 atmosphere (50 psi/25° C.) for 12 h. The catalyst was filtered, and the filtrate was concentrated under the reduced pressure to dryness to give the product of Step C (20 g, 93.0%). 1H NMR (400 MHz, DMSO-d6) δ ppm 6.95-7.10 (m, 2H), 3.86 (s, 3H)
