- W1979057037 abstract "Abstract A method is described for the isolation in high yield and purity of an intermediate acid hydrolysis product of nitrazepam. The compound is obtained in maximum yield by heating a solution of nitrazepam in 0.1 M hydrochloric acid at 80°C for 45 min and is isolated by a fast solvent extraction procedure to minimise further hydrolysis to 2-amino-5-nitrobenzophenone. Structural elucidation by infrared spectrometry, proton magnetic resonance spectrometry and elemental analysis has confirmed that the product is 2-glycylamino-5-nitrobenzophenone formed by cleavage of the 4,5-azomethine bond of nitrazepam." @default.
