| Abstract: | 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-pyrimido4,5-b]1,5]benzodiazepine derivatives. Structures of the products confirmed by 1HNMR, IR, and mass spectra. |
