反応手順

Lithium aluminium hydride (2 g, 51 mmol) is added in small portions to anhydrous ethyl ether (200 cc). The mixture is cooled to 0° C. and ethyl 3,3-ethylenedioxybutanoate (3 g, 17 mmol) is then added over 10 minutes as a solution in anhydrous ethyl ether (10 cc). The mixture is stirred for 2 hours 30 minutes at a temperature in the region of 20° C. and is then hydrolysed by adding a saturated sodium sulphate solution (12 cc). After 2 hours the white precipitate is separated off by filtration. The organic phases are dried over magnesium sulphate. 2,2-Ethylenedioxy-4-hydroxybutane (2.22 g) is thus obtained.
