Reaction Steps
A solution of 2-nitrophenol (1.55 g, 11.2 mmol) and methyl 4-chlorocarbonyl benzoate (2.44 g, 12.2 mmol) in THF (14 mL) and pyridine (2.8 mL) was stirred for 2 h at room temperature. The reaction was diluted with saturated sodium bicarbonate (30 mL) and EtOAc (20 mL), the phases separated and the aqueous phase extracted with EtOAc (2×15 mL). The combined organic extracts were dried (Na2SO4), filtered and concentrated under reduced pressure to afford terephthalic acid 1-methyl ester 4-(2-nitrophenyl)ester (3.15 g, 94%). 1H NMR (CDCl3) δ 3.98 (s, 3H), 7.43 (d, 1H, J=7.8 Hz), 7.48 (t, 1H, J=7.8 Hz), 7.73 (t, 1H, J=7.8 Hz), 8.20 (m, 4H), 8.27 (m, 1H).
