Reaction Conditions

Reaction Steps

To 75 ml of N,N-dimethylformamide were added 3.00 g of 2,4-dibromothiazole, 1.74 g of phenol, and 3.44 g of potassium carbonate, and the mixture was stirred at 140° C. for 6 hours. After cooling to room temperature, 100 ml of water was added to the reaction mixture and two extractions were conducted with 100 ml of ethyl acetate. After being washed twice with 100 ml of water and once with 50 ml of saturated brine, the organic layer was dried over magnesium sulfate. After filtering the magnesium sulfate, the organic layer was concentrated and the residue was purified by column chromatography (Wakogel C-200; hexane:ethyl acetate=9:1) to give 2.86 g of an ether compound.
