Reaction Steps

1-bromo-5-isopropyl-2,4-bis-methoxymethoxy-benzene (IM2-a: 12.0 g, 37.8 mmol) and tetrahydrofuran (150 mL) were placed in a 300 mL three-neck flask and cooled to −60° C. To this mixture a hexane solution of N-butyllithium (24 mL, 1.59 M) was added slowly, and after adjusting the temperature of the solution to −40° C. the mixture was stirred for 1 hour. Dry ice powder was added to the reaction mixture and the reaction mixture was allowed to come to room temperature. After completing the reaction, the reaction mixture was mixed with distilled water and extracted with ethyl acetate. The extracted organic layer was dried over anhydrous sodium sulfate. After filtration and evaporation, the solid material obtained was purified by suspending in hexane to obtain the title compound (IM3-a: 6.6 g, 62%).
