In the reaction of 7-chloro-1,5-benzodiazepine-2,4-dione with N,N-dimethylformamide/dimethylacetal, the diazepine seven-membered ring undergoes a contraction to form the five-membered ring. The reaction yields two isomers the title compound, C13H14ClN3O2; the major component has the chlorine-atom su...

description In the reaction of 7-chloro-1,5-benzodiazepine-2,4-dione with N,N-dimethylformamide/dimethylacetal, the diazepine seven-membered ring undergoes a contraction to form the five-membered ring. The reaction yields two isomers the title compound, C13H14ClN3O2; the major component has the chlorine-atom substituent in the 5-position of the benzimidazolone ring and the minor component has the chlorine atom in the 6-position. The two isomers form a disordered co-crystal, the chloromethylbenzimidazolone portion of both components are disordered with respect to each other in a 4:1 ratio [the refined ratio is 0.816 (5):0.184 (5)]; the dimethylaminocryloyl substitutent is ordered. The double bond of the dimethylaminoacryloyl substituent has an E configuration.
