Used Chemicals
Procedure
(3-Formylphenyl)boronic acid (480 mg, 3.2 mmol) and 4-chloro-3,5-dimethyl-phenol (500 mg, 3.2 mmol) and tetrakis(triphenylphosphine)palladium(0) (55 mg, 0.048 mmol, 1.5 mol%) were dissolved in degassed ethanol (20 mL). A solution of sodium carbonate (250 mg, 2.4 mmol) in water (5 mL) was added to the solution, and the mixture was stirred for 5 h at 75 °C. The reaction mixture was cooled to room temperature and filtered. The filtrate was concentrated, cooled Et2O (15 mL) was added and filtered to remove insoluble. The filtrate was concentrated to give the desired product as a pale yellow crystalline solid (506 mg, 2.24 mmol, 70%).
Experimenter's Comments
Ethanol was degassed by purging with N2.
The reaction mixture was monitored by TLC (hexane : ethyl acetate = 2 : 3, Rf = 0.8).
