Novel 3-amino-1-benzoxepine derivatives and methods for their production are disclosed. These derivatives correspond to the Formula I ##STR1## wherein: R.sub.1 and R.sub.2 independently of one another are hydrogen, C.sub.1 -C.sub.5 alkyl, C.sub.1 -C.sub.5 alkyl substituted with a terminal phenyl, or a phenyl containing one or two halogens, methyl or methoxy groups, a 3,4-methylenedioxy or a 3,4-ethylenedioxy group, C.sub.2 -C.sub.5 alkyl substituted with terminal hydroxy or methoxy or, C.sub.3 -C.sub.4 alkenyl; or one of R.sub.1 and R.sub.2 are hydrogen or a C.sub.1 -C.sub.5 alkyl and the other is a C.sub.2 -C.sub.5 alkyl substituted with a terminal NR.sub.7 R.sub.8 ; R.sub.7 and R.sub.8 independently of one another are hydrogen or C.sub.1 -C.sub.5 alkyl; or R.sub.7 and R.sub.8 are together a 5 to 7 member ring or said ring having heterogeneous oxygen, sulfur or nitrogen, or R.sub.1 and R.sub.2 are together a 5 to 7 member ring or said ring having heterogeneous oxygen, sulfur or NR.sub.9 ; R.sub.9 is hydrogen, methyl, benzyl, or phenyl; one of R.sub.3 and R.sub.4 is hydrogen and the other hydroxy, or R.sub.3 and R.sub.4 together are oxygen; R.sub.5 and R.sub.6 independently of one another are hydrogen, halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy or C.sub.1 -C.sub.4 alkylthio; or one of R.sub.5 and R.sub.6 is trifluoromethyl or nitro and the other is hydrogen; the stereo isomers and the acid addition salts thereof. These compounds have a favorable effect upon the motility of the gastro-intestinal tract and, therefore, constitute the active ingredient of pharmaceutical compositions and methods for the treatment of motility disorders.
