Participants

Reaction Steps

This compound was prepared in a manner similar to that of methyl 5′-Fluoro-2′-methoxy-4-nitro-2-biphenylcarboxylate (EXAMPLE 107) from methyl 2-bromo-5-nitrobenzoate (2.46 g, 9.46 mmol), (PPh3)4Pd (0.33 g, 0.28 mmol), and 2,5-dimethoxyphenylboronic acid (2.42 g, 13.3 mmol) to afford 2.08 g (69%) of methyl (2′,5′-dimethoxy-4-nitro-2-biphenylcarboxylate) as a white solid. Data for methyl (2′,5′-dimethoxy-4-nitro-2-biphenylcarboxylate): 1H NMR (400 MHz, CDCl3) 8.70 (d, J=2.4, 1H), 8.37 (dd, J=8.4, 2.5, 1H), 7.52 (d, J=8.5, 1H), 6.92 (dd, J=8.8, 3.0, 1H), 6.84 (m, 1H), 3.82 (s, 3H), 3.75 (s, 3H), 3.67 (s, 3H).
