Ammonia → 3-Benzyl-1,2,4-oxadiazol-5-amine

Participants

Reaction Steps

A mixture of 60 g. (0.22 moles) of 3-(phenylmethyl)-5-trichloromethyl-1,2,4-oxadiazole and 50 ml. of ether are added dropwise with stirring into 100 ml. of liquid ammonia and stirred for an additional hour. The ammonia and ether are evaporated, the residue is treated with a little water and filtered under suction. 33.3 g. of 5-amino-3-(phenylmethyl)-1,2,4-oxadiazole are obtained, m.p. 142°-145°. After recrystallization from ethanol the compound melts at 145°-146°.
