Reaction Steps
To each pharmaceutical composition (500 mg) of DMDC 2H2O packed in vials or ampoules in Examples 3 to 8 was added 10 ml of 1 w/v % aqueous lactic acid for dissolution to give injections of DMDC 2H2O. The same procedure was repeated using 3 w/v % aqueous citric acid, 5 w/v % aqueous maleic acid, 6 w/v % aqueous tartaric acid or 10 w/v % aqueous acetic acid to give injections of DMDC 2H2O.
