Novel 2-acyl amino methyl-5-phenyl-1H-2,3-dihydro-1,4-benzo diazepine compounds of the following Formula I ##STR1## which have valuable pharmacological properties are provided. In said Formula I the acyl group --CO--R.sub.3 represents a benzoyl group or a phenyl alkanoyl group which may be unsubstituted or mono- or di-substituted in the phenyl ring. The substituent R.sub.1 in said compounds indicates lower alkyl, lower alkenyl, or cyclopropyl methyl, and the substituent R.sub.2 indicates hydrogen, lower alkyl, or lower alkenyl, while the substituent R.sub.6 indicates hydrogen, halogen, lower alkyl, lower alkoxy, hydroxyl, lower alkylthio, nitro, trifluoro methyl, cyano, amino, mono- or di-lower alkyl amino, lower mono-alkanoyl amino, lower N-alkyl-N-alkanoyl amino, or lower alkanoyloxy, and the substituent R.sub.7 indicates hydrogen, halogen, lower alkyl, lower alkoxy, hydroxyl, or lower alkanoyloxy, whereby R.sub.6 and R.sub.7, when attached to adjacent carbon atoms, may form together the methylene dioxy or the ethylene dioxy group. The substituents R.sub.8 and R.sub.9 designate the same substituents as indicated for the substituents R.sub.6 and R.sub.7. The compounds of Formula I have a surprising analgesic activity.
