Synthetic intermediates of 1,4-benzodiazepines

This book describes the synthesis of amidines and imidate esters from 2-oxy/amino-4'-benzonitrile, thiosemicarbazone from 2-oxy-4'-benzaldehyde, dimethylaminomethylene ketone and chalcone from 2-oxy-4'-acetylphenyl derivatives of 1,4-benzodiazepine (2.094-2.100). The structures of all compounds have been established by elemental analysis (Carbon, Hydrogen, Nitrogen and Sulfur), IR, 1H NMR, and Mass spectral data.
