Reaction Steps
To 1.03 g of 4,6-di-t-butyl-5-hydroxy-2,2-di-n-pentyl-2,3-dihydrobenzofuran synthesized according to JP No. 6-206842A/94 dissolved in 15 ml of dichloromethane was added 7 drops of methanesulfonic acid and the mixture was stirred at room temperature for a whole day and night. Then, the reaction mixture was combined with water and extracted with dichloromethane. The extracted layers were washed with saturated brine, dried over anhydrous magnesium sulfate and then concentrated. The concentrate was purified by silica gel column chromatography (in n-hexane containing 10% ethyl acetate) to give 0.19 g of 6-t-butyl-5-hydroxy-2,2-di-n-pentyl-2,3-dihydrobenzofuran as a colorless oil (yield 22%).
