Ethanol → Methyl 3-phenylbenzoate

Participants

Reaction Steps

Using Preparation Method 2, Methyl 3-bromobenzoate (3.86 g, 18.6 mmol) was reacted with phenyl boronic acid (2.4 g, 20.5 mmol) in the presence of 5 mol % Pd(PPh3)4, 18 mL of 2N Na2CO3, 9.4 mL of Ethanol and 37 mL of toluene. The resulting reaction mixture was purified using SiO2 with hexane/diethyl ether 98:2 to give a colourless thick oil (389 g, 96%). NMR 1H (ppm, CDCl3): 8.29 (s, 1H), 8.03 (d, J3=7.8 Hz, 1H), 7.79 (d, J3=7.8 Hz, 1H), 7.63 (d, J3=7.2 Hz, 2H), 7.54-7.26 (m, 4H), 3.96 (s, 3H). MS: M+1 463.2.
