A solution of 73.4 g of 2-(2,2-dimethyl-1,3-dioxolan-4-yl)ethylene oxide in 400 ml of 25% strength ammonia is heated in an autoclave for 4 hours to 130° C. The slightly yellowish solution is concentrated to dryness under vacuum; during this step, the residue crystallizes. 2-Amino-1-(2,2-dimethyl-1,3-dioxolan-4-yl)ethanol is re-crystallized from ethanol/ether, mp 94°-96° C.
