Sodium Sulfate → 3,5-Dimethyl-4-(hydroxymethyl)isoxazole

참여 물질

반응 단계

To a suspension of 23.53 g of lithium aluminum hydride in 600 ml of ether was added dropwise 64 g of 4-carbethoxy-3,5-dimethylisoxazole in 100 ml of ether at a rate so that gentle reflux occurred. The addition was complete in about two hours, and the mixture was stirred overnight under nitrogen. A saturated solution of sodium sulfate was added dropwise under nitrogen until the excess lithium aluminum hydride was decomposed. The resulting suspension was filtered and the filtrate concentrated to an oil which was distilled to give 36.4 g of 3,5-dimethyl-4-hydroxymethylisoxazole, b.p. 130°-140° C. (0.1 mm).
