Abstract
Disclosed herein are 1-aminoalkyl-3,4-dihydronaphthalenes represented by the formula ##STR1## wherein n is 1 or 2; R, R.sub.1, and R.sub.2 are independently selected from hydrogen, hydroxy, loweralkoxy of 1 to 3 carbon atoms, loweralkenyloxy of 1 to 3 carbon atoms, thiomethyl, halo, or ##STR2## wherein R.sub.5 and R.sub.6 are independently selected from hydrogen, loweracyl of 1 to 4 carbon atoms or sulfonyl of the formula ##STR3## wherein R.sub.7 is loweralkyl of 1 to 4 carbon atoms; or R and R.sub.1, or R.sub.1 and R.sub.2 can be taken together to form a methylenedioxy or ethylenedioxy bridge; with the proviso that at least one of R, R.sub.1 or R.sub.2 must be other than hydrogen; and R.sub.3 and R.sub.4 are independently selected from hydrogen; loweralkyl of 1 to 4 carbon atoms; halo-substituted loweralkyl of 1 to 4 carbon atoms; arylalkyl of the formula ##STR4## wherein m is 0, 1 or 2, p is 0 or 1, R.sub.8 is hydrogen or loweralkyl of 1 to 4 carbon atoms and R.sub.9 and R.sub.10 are independently selected from hydrogen, hydroxy, methoxy, loweralkyl of 1 to 4 carbon atoms, or halo, or R.sub.9 and R.sub.10 can be taken together to form a methylenedioxy or ethylenedioxy bridge; or …
