Toluene → 2-Methoxy-4-phenylbenzaldehyde

Participants

Reaction Steps

A mixture of toluene (30 mL) and water (5 mL) was degassed with nitrogen for 30 min. A mixture of sodium carbonate (2.26 g, 6.9 mmol) was added followed by 2-methoxy-4-bromobenzaldehyde (0.5 g, 2.3 mmol), phenylboronic acid (0.337 g, 2.7 mmol) and tetrakis triphenyl phosphene palladium(0) (0.261 g, 0.022 mmol) to the above degassed water/toluene mixture. The reaction mixture was then refluxed overnight. After the reaction is completed, it was cooled to room temperature and extracted with ethyl acetate. The combined organic layers were dried over sodium sulphate and concentrated. The obtained residue was purified by column chromatography using 3% ethyl acetate in hexane to obtain the title compound.
