Synthetic intermediates of 14-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 14-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.
