Reaction Steps

A solution of 10 parts of ethyl 5-{3-[4-azatricyclo(4.3.1.13,8)undecan-4-yl]-1,1-diphenylpropyl}-1,3,4-oxadiazole-2-carboxylate in a minimal amount of diethyl ether is acidified with a solution of hydrogen chloride in 2-propanol. The precipitate which forms is filtered off and recrystallized from a mixture of ethanol and ether to give ethyl 5-{3-[4-azatricyclo(4.3.1.13,8)-undecan-4-yl]-1,1-diphenylpropyl}-1,3,4-oxadiazole-2-carboxylate hydrochloride as yellow-green crystals melting at approximately 199°-200°.
