YieldReaction ConditionsOperation in experiment
95% With dmap; dicyclohexyl-carbodiimide; In dichloromethane; at 20℃; for 12h;Inert atmosphere; Ethyl 4-vinyl benzoate was synthesized according to a reported modified procedure. 1H NMR match previously reported data. Under a nitrogen atmosphere, 4-vinyl benzoic acid (1.00 g, 6.75 mmol), 1,3-dicyclohexyl-carbodiimide (1.67 g, 8.10 mmol), and 4-dimethylaminopyridine (82.5 mg, 0.675 mmol) were added to a 100 mL round-bottom flask equipped with a magnetic stir bar. To this mixture were added CH2Cl2 (50 mL) and ethanol (2.90 g, 67.5 mmol). The resulting solution was stirred under nitrogen for 12 h at RT, filtered through a Celite pad, and evaporated to near dryness under vacuum. Chromatography of the crude product on silica (Hexane: EtOAc=30:1), followed by concentration gave a primrose yellow oil (1.13 g, 95%). 1H NMR (400 MHz, CDCl3): delta 7.78 (d, 2H, J = 8.5 Hz, ArH), 7.24 (d, 2H, J = 8.0 Hz, ArH), 6.51 (dd, 1H, J1 = 11 Hz, J2 = 18 Hz, CH=CH2), 5.63 (d, 1H, J = 18 Hz, CH=CH2), 5.16 (d, 1H, J = 11 Hz, CH=CH2), 4.16 (q, 2H, J = 7.5 Hz, CH2CH3), 1.19 (t, 3H, J = 7.0 Hz, CH2CH3).

The THF was removed under reduced pressure, and the product was purified by flash chromatography with CH2Cl2/MeOH (100:0-99:1) as the eluent. The crude material was recrystallized from CH2Cl2/EtOH to give yellow ester (541.2 mg, 82%) as a bright yellow solid. 1H NMR (600 MHz, CDCl3): δ 1.42 (t, J= 7.1 Hz, 12H, CH3), 4.41 (q, J= 7.1 Hz, 8H, CH2), 7.14 (d, J= 16 Hz, 4H, vinyl CH), 7.57 (d, J= 16.1 Hz, 4H, vinyl CH), 7.61 (d, J= 8.3 Hz, 8H, ArH), 7.86 (s, 2H, core ArH), 8.07(d, J= 8.3 Hz, 8H, ArH).
