To an ice-cold slurry of 50.0 g. (1.28 moles) of lithium aluminum hydride in one liter of ether, 330 g. (3.60 moles) of chloroacetone was added over a period of one hour. The reaction mixture was allowed to stand for half an hour before decomposition of the excess hydride with water. Sufficient sulfuric acid (4 N) was then added to give a separable mixture. The ether layer was decanted and the aqueous layer extracted with three 300-ml. portions of ether. The combined ether layers were dried, first over sodium sulfate, then over magnesium sulfate. The ether was removed on a steam-bath, and the remaining liquid was distilled at reduced pressure to give 150 g. (44%) of crude material boiling at 50.6—50.8° at 30 mm. when fractionated through a 100-cm. glass-bead column.
