Versuchsvorschrift
4-Bromobenzenethiol (3.78 g, 0.02 mol) was added to a solution of sodium (0.46 g, 0.02 mol) in ethanol (50 ml.) and 3,5-di-(chloromethyl)-1,2,4-oxadiazole (1.67 g, 0.01 mol) was added dropwise. The solution was then filtered and evaporated to give a solid which was recrystallised from isopropanol to give 3,5-di-(4-bromophenylthiomethyl)-1,2,4-oxadiazole, m.p. 80°.
