Ethylene carbonate → 4-(Dec-1-yl)-2-oxo-1,3-oxazolidine

Participants

Reaction Steps

26.465 g of 2-aminododecanol and 12.32 g of ethylene carbonate were heated at approximately 110° C. for 48 hours (preparation of the cyclic urethanes can be carried out without a solvent or in toluene solution)as a solvent. The reaction was followed by tlc and at the completion of the reaction the contents were cooled, dissolved in ethyl acetate and the organic solution was washed with brine and water. After drying, the filtrate was concentrated and the oily residue was kugelrohr distilled to give 27.33 g (96.56%) of colorless liquid, which slowly solidified, m.p. 31.5-32.5° C.
