Novel, 3-amino-1-benzoxepin-5(2H)-one 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.3 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.5 R.sub.6 ; R.sub.5 and R.sub.6 independently of one another are hydrogen or C.sub.1 -C.sub.5 alkyl; or R.sub.5 and R.sub.6 are together a 5 or 7 member ring, or R.sub.5 and R.sub.6 are together a 5 to 7 member ring having heterogeneous oxygen, sulfur or nitrogen; R.sub.1 and R.sub.2 are together a 5 to 7 member ring, or R.sub.1 and R.sub.2 are together a 5 to 7 member ring having heterogeneous oxygen, sulfur or NR.sub.7 ; R.sub.7 is hydrogen, methyl, benzyl or phenyl; R.sub.3 and R.sub.4 are 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.3 and R.sub.4 is trifluoromethyl or nitro and the other is hydrogen; and the acid addition salts thereof. These compounds have a favorable effect on the treatment of spasms of the stomach-intestinal tract and, therefore, constitute the active ingredient of pharmaceutical compositions and methods for the treatment of disorders of the stomach and intestinal tract. Processes for the preparation of the derivatives and their acid addition salts and intermediate products for their preparation are also described.
