Indole-3-carboxaldehydes (1a-d) undergo condensation with ethyl cyanoacetate and malononitrile to give the acrylonitrile 2a-d and 3a-d which on reaction with hydrazine hydrate yield 3,5-diamino-5-hydroxy-4-(3-indolylmethylene)pyrazoles (4a-d) and 3-amino-5-hydroxy -4-(3-indolylmethylene)pyrazoles (5a-d), respectively. The new compounds were also screened for their antibacterial activity.
Keywords: Indole-3-carboxaldehydes ; Active methylene compounds; Base; Hydrazine hydrate; Pyrazoles.
