prompted investigation of other p-phenethylamines with these ring substituents. The three new p-phenethylamines described in this communication, 3, 4-dimethyl-, 3, 4-dichloro-, and 3, 5-dimethoxy-4-methyl-, all induced a strong rage response in cats. These findings confirmed previous observations that the substitution of methyl or chloro groups in the 3-and 4-positions of the p-phenethylamine molecule results in compounds which produce a rage ...
