Stirring was continued for one night and 500 ml. of water were then added to the reaction mixture. The organic layer was separated and, after the usual treatments, distilled to give 98 g. (83 %) of two diastereoisomers of the epoxy product. V.p.c. enabled the separation of the two isomers (Carbowax, 170°, 3 m)
