Procedure

A sample of 14.00 grams of 2,2-bis(trifluoromethyl)-4-tosyloxymethyl-1,3-dioxolane (m.p. 58°-60° C.) is dissolved in 40 ml of dimethylformamide and 4.85 grams NaN3 is added. The mixture is stirred magnetically at 140°-149° C. for 3.5 hours. The product is diluted with benzene and filtered. The filtrate is washed thoroughly with water, vacuum-stripped and distilled. The product, 2,2-bis(trifluoromethyl)-4-azidomethyl-1,3-dioxolane, has a boiling point of 78° C./20 mm Hg and a refractive index of 1.37447 at 20° C.
