Reaction Conditions

Reaction Steps

2-Bromo-4,6-dimethylphenol (500 mg, 2.49 mmol), 2-thiophenyl boronic acid (88 mg, 2.99 mmol), sodium carbonate (791 mg, 7.47 mmol) and Pd2(dppf)2Cl2 (406 mg, 0.49 mmol) were dissolved in dimethoxyethane/water 6 mL/3 mL, followed by stirring in microwave at 120° C. for 20 minutes. After the completion of the reaction, the reaction mixture was filtered using Celite. The filtrate was added with water, and extracted with ethyl acetate. The obtained organic layer was dried over magnesium sulfate, and purified by column chromatography (ethyl acetate:hexane=1:3) to obtain 2,4-dimethyl-6-(thiophene-2-yl)phenol (231 mg, 45%).
