Procedure

7.3 gm of guanidine hydrochloride were added in portions to a solution of 1.8 gm of sodium in 100 ml of ethanol. After 30 minutes of stirring, 22.5 gm of 3-(3-nitro-phenyl)-5-trichloromethyl-1,2,4-oxadiazole were added. The solid which separated out overnight was filtered off and dried, yielding 15.2 gm of the title compound, m.p. 290°-291° C.
