    Abstract: 1345443 Phosphorus-containing benzodiazepine derivatives FARBWERKE HOECHST AG 5 May 1971 [8 May 1970 23 Sept 1970] 13207/71 Heading C2P [Also in Division A5] The invention comprises a phosphorus-containing benzodiazepine derivative of the general formula wherein R 1 is H, NO 2 , a halogen atom, or CF 3 , R 2 is a straight or branched chain alkyl group having up to 8 carbon atoms, a hydrogen atom, a halogen atom, NO 2 or CF 3 , R 3 is a straight chain or branched chain alkyl group having up to 3 carbon atoms and n is an integer from 1 to 6: They may be obtained by (a) reacting a metal derivative of the formula wherein M is a metal cation with a phosphine oxide of the formula X(CH 2 ) n P(O)(R 3 ) 2 , wherein X is a halogen atom or an alkyl (or aryl-) sulphonyloxy group, or (b) by reacting a compound of the formula with a derivative of amino acetic acid (preferably an ester, e.g. an imino or ortho ester derivative) or (c) by reacting a compound of the above Formula IV with a halide or azide of a halogenoacetic acid, treating the product with ammonia and then cyclizing the compound so obtained. In reaction (a) the metal compound can first be formed by heating the appropriate 1-unsubstituted benzodiazepine with, e.g., Ca-, Na- or Li-hydride or with potassium tertbutylate or sodium methylate in an inert organic solvent and the product may then be formed directly by reaction with the compound X(CH 2 ) n P(O)(R 3 ) 2 in the same solvent without isolation of the metal derivative. The products are useful as tranquillizers.
