I found this interesting, so I decided to post it here:
4-(substituted alkoxy)-4-(substituted phenyl)cyclohexylamines
Patent US3965180
This invention relates to novel 4-(substituted alkoxy)-4-(substituted phenyl)cyclohexylamines embraced by the formula WHEREIN DIFFERENCE IS A GENERIC EXPRESSION DENOTING CIS AND TRANS STEREOCONFIGURATION AND MIXTURES THEREOF, WITH THE PROVISO THAT WHEN THE STEREOCONFIGURATION OF THE LINKAGE CONNECTING THE CYCLOHEXANE RING AND R3O is is cis to the amino group, the linkage connecting the cyclohexane and phenyl rings is always trans, and vice versa; R is selected from the group consisting of lower alkyl of 1 through 4 carbon atoms, chlorine, fluorine, bromine, trifluoromethyl, and lower alkoxy of 1 through 4 carbon atoms; R' has the same meaning as R and in addition hydrogen; R1 is selected from the group consisting of hydrogen and lower alkyl of 1 through 4 carbon atoms; R2 is selected from the group consisting of hydrogen, lower alkyl of 1 through 4 carbon atoms, ring monosubstituted aroylalkyl wherein the substituents have the same meaning as R and R', above, aryl is from 6 through 10 carbon atoms and alkyl of from 1 through 4 carbon atoms and bis (ring monosubstituted)arylalkyl wherein the substituents have the same meaning as R and R', above, aryl is from 6 through 10 carbon atoms and alkyl of from 1 through 4 carbon atoms; R1 and R2 taken together with -N< is a saturated heterocyclic amino radical selected from the group consisting of unsubstituted and monosubstituted pyrrolidino, piperidino, hexamethyleneimino, morpholino and piperazino; R3 is lower alkyl of 1 through 4 carbon atoms; and an acid addition salt thereof. It also relates to intermediates and processes for the preparation of the aforesaid novel compounds (1) and novel derivatives thereof. The systemic administration to humans and animals of the novel compounds (1) depresses their central nervous systems.
Love my country, fear my government.
