实验过程

This compound was prepared by the procedure for butyl 4′-(trifluoromethyl)biphenyl-4-carboxylate (CS-16), except using butyl 3-iodobenzoate instead of butyl 4-iodobenzoate. The product was purified by column chromatography followed by vacuum distillation, collecting fraction bp 127-131° C./0.12 mm. The product was a colorless oil, and obtained in 40% yield. 1H NMR (CDCl3): δ 0.99 (t, 3H), 1.5 (m, 2H), 1.8 (m, 2H), 4.37 (t, 2H), 7.54 (d, 2H), 7.72 (s, 4H), 7.77 (d, 2H), 8.09 (d, 2H), 8.28 (s, 2H).
