実験手順
To a suspension of 7.6 g of lithium aluminium hydride in 250 ml of tetrahydrofuran was added a solution of 64.9 g of methyl 5-methyl-3-isoxazolepropanoate in 100 ml of tetrahydrofuran. The reaction mixture was stirred at reflux for three hours, then cooled and 15.2 ml of water in 30 ml of tetrahydrofuran added. The mixture was filtered and the filtrate concentrated in vacuo. The residue was distilled to give 44.1 g of 5-methyl-3-(3-hydroxypropyl)isoxazole, b.p. 84°-85° C.(0.1 mm).
