実験手順

After dissolving 3 g of 2-allyl-4-bromo-6-methoxy-phenol [CAS No. 352019-92-2] in 10 ml of DMF, 1.3 g of imidazole and 2 g of chlorotriisopropylsilane were added and the mixture was stirred at 50° C. for 4 hours. Next, 1N hydrochloric acid was added to the reaction mixture and extraction was performed with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate. The desiccating agent was filtered off, and the filtrate was concentrated under reduced pressure to give (2-allyl-4-bromo-6-methoxyphenoxy)triisopropylsilane.
