Benzodiazocines corresponding to the formula ##STR1## are converted to benzodiazepines corresponding to the formula ##STR2## of claim 1 by subjecting the benzodiazocine (a) if it is halogen-substituted in the 3-position to a thermal treatment which may also take place in the presence of a nucleophilic agent for the reaction or (b) if the 3-position is hydroxy substituted to treatment with a Lewis acid which is a chlorinating or brominating agent. Whenever the diazepine obtained as the final product has a 2-halogenomethyl group it may then be converted to benzodiazepine which is otherwise substituted in the 2-position.

Process of making benzodiazepine derivatives

1,4-Benzodiazepin of the formula ##STR1## wherein R is a low molecular straight or branched alkyl and X is halogen or trifluoromethyl, and pharmaceutically acceptable acid addition salts of these benzodiazepins. The benzodiazepins are made by heating an acyldiamine in the presence of phosphorus oxychloride at the latter's boiling point followed by reacting the resulting mixture of 7-member and 8-member compounds with an alkali metal alkoxide.

Benzodiazepine derivatives and process of making them

1,2,3,4-Tetrahydro-1,5-benzodiazocines having the following formula ##STR1## in which R.sup.1 is a hydrogen, alkyl radical having at most 6 carbon atoms, methoxyethyl, or benzyl radical,

Bendodiazocine derivatives and process of making the same

A 1,3 diaminopropane derivative having the formula I ##STR1## in which R.sub.1 is hydrogen, methoxyethyl, benzyl or alkyl of at most 6 carbon atoms or is cycloalkyl of 3 to 6 carbon atoms,

1,3 Diaminopropane derivatives

1,4-benzodiazepin of the formula ##STR1## wherein R is a low molecular straight or branched alkyl and X is halogen or trifluoromethyl, and pharmaceutically acceptable acid addition salts of these benzodiazepins. The benzodiazepins are made by heating an acyldiamine in the presence of phosphorus oxychloride at the latter's boiling point followed by reacting the resulting mixture of 7-member and 8-member compounds with an alkali metal alkoxide.

Benzodiazepin derivatives

A benzodiazepine derivative of the formula ##STR1## wherein R.sub.1 is hydrogen, lower alkyl which may be a straight chain, branched chain or cyclic group and may also be substituted,

Process for making benzodiazepine derivatives

A freely flowable pancreatin of high amylolytic, lipolytic, and proteolytic activity, of a low germ content and substantially free of pathogenic germs and fibrous tissue material, of a high bulk weight between about 500 g./liter and about 700 g./liter and a very fine particulate size is produced according to the continuous process of extracting finely comminuted pancreas glands with a mixture of chlorinated hydrocarbons and fluoro-chloro-carbons and, if required, water, separating the fat-containing solvent phase, and recovering pancreatin from the enzyme phase.
