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).

Application
Palladium-Catalyzed Three-Component Reaction for the Synthesis of Imidazolidinones
Typical Procedure: Once the Schlenk tube containing K2CO3 (55 mg, 0.40 mmol) is flamed, dried, and filled with argon, Pd(PPh3)4 (12 mg, 0.010 mmol), PMB-protected 2,3-allenylamine (37 mg, 0.20 mmol), iodobenzene (58 mg, 0.28 mmol), phenyl isocyanate (36 mg, 0.30 mmol), and CH3CN (4 mL) are added sequentially. The resulting solution is heated to and stirred at 70°C. When the reaction is completed as monitored by TLC, the solvent is evaporated under reduced pressure, and the residue is purified by chromatography on silica gel (petroleum ether : ethyl acetate = 7:1) to afford the corresponding imidazolidione (72 mg, Y. 96%) as an oil.
