3,2-Benzoxazepines of the formula ##STR1## and their preparation. In formula (I), R respesents hydrogen or lower alkyl; R.sup.1 represents hydrogen, lower alkyl, lower alkenyl, hydroxy-lower alkyl, carbamyloxy-lower alkyl, acyl, amidino, carbamyl, mono- or di-substituted carbamyl; R.sup.2 may be in position 7 or 8 of the benzoxazepine ring and represents hydrogen, nitro, amino, acetamino or halo. The compounds are prepared by reacting 1,2,4,5-tetrahydro-3,2-benzoxazepine with a reactant which reacts with a secondary amino group to give substitution in the 2-position. The compounds have anti-inflammatory and central nervous system activity.
