Reaction of 4,6‐dichloropyrimidine‐5‐carbaldehyde with amines in chloroform gave 4‐(substitutedamino)‐6‐chloro‐pyrimidine‐5‐carbaldehydes derivatives at low temperature. Treatment of the latter products with 2‐aminobenzenethiol in alkaline benzene and then in boiling acetonitrile gave a novel group of 11H‐pyrimido[4,5‐ b ][1,5]benzodiazepine derivatives. Structures of the products confirmed by 1 HNMR, IR, and mass spectra.
