Participants

Reaction Steps

4-Iodo-2-methylphenol (15.0 g, 64.1 mmol) was dissolved in N,N-dimethylformamide (250 ml), and imidazole (8.7 g, 128.2 mmol, 2.0 eq.) added to the mixture, tert-Butyldimethyl silyl chloride (10.6 g, 70.5 mmol, 1.1 eq.) was slowly added to the above mixture and stirred at room temperature for 4 hours. After completion of the reaction, the reaction mixture was extracted with aqueous ammonium chloride solution and ethyl acetate, and dried over magnesium sulfate. The crude product was purified on silica flash column. The solvent was evaporated under reduced pressure to thereby yield 21.8 g of the title compound (yield: 97.5%).
