Procedure

A mixture of 61 g. (0.63 mole) of 1-ethylpyrroline, 50 ml. of concentrated aqueous hydrochloric acid and 600 ml. of water was treated with chlorine gas for 2.5 hr. The mixture was filtered through cotton and the filtrate was washed with two 100-ml. portions of methylene chloride. The aqueous layer was made basic with 20% sodium hydroxide, heated on a steam bath for 0.5 hr. and extracted with three 100-ml. portions of methylene chloride. The combined extracts were dried over anhydrous sodium sulfate and concentrated and the residue vacuum distilled to give 39.4 g. (56%) of the epoxide as a clear oil (b.p. 75°-90° @ 28 mm). The epoxide was converted to the oxalate and the salt was recrystallized from absolute ethanol to give white needles, m.p. 142°-4°d.
