Diisobutylaluminumhydride → HCID 23442890, compound

Participants

Reaction Steps

Under a nitrogen stream, 0.15 g of 6-t-butyl-2-methy-5-trimethylacetoxy-2,3-dihydrobenzofuran was dissolved in 3 ml of n-hexane at room temperature, 1.55 ml of diisobutylaluminium hydride (1M in n-hexane) was added dropwise, and the mixture was stirred overnight. After the reaction was quenched with 5% hydrochloric acid, the mixture was extracted with water and ethyl acetate. The organic layers were washed with saturated brine, dried over anhydrous magnesium sulfate and then concentrated. The concentrate was purified on a short column of silica gel (in n-hexane containing 5% ethyl acetate) to give 0.09 g of 6-t-butyl-5-hydroxy-2-methyl-2,3-dihydrobenzofuran as a white solid (yield 84%).
