15317-58-5, 1H-Indole-3-carbohydrazide is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General procedure: 1H-Indole-3-carboxylate methylester 2 (1.0 mmol-equiv.) was refluxed with hydrazine hydrate(12.5 g, 0.25 M) in appropriate ethanol (30 mL) for 2 h. The progressof the reaction was monitored by TLC. After cooling the reactionmixture to room temperature, the mixtures were filtered to givewhite solid crude products without purification. Next, indolehydrazide(3, 1.0 mmol) in ethanol (30 mL) was added dropwiseinto the appropriate aldehyde (1.5 mmol-equiv.) and a few drops ofpropionic acid; the mixture was stirred and refluxed for 2.5 h. Aftercooling, the precipitates were filtered and washed several times bymethanol to yield the crystal substances 4aeu.

15317-58-5 1H-Indole-3-carbohydrazide 27199, aindole-building-block compound, is more and more widely used in various.

15317-58-5, 1H-Indole-3-carbohydrazide is a indole-building-block compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

General Procedure: To a mixture of indole-3-carboxaldehyde 2 (1 mmol) and indole-3-carbohydrazide 4 (1 mmol) in ethanol(10 mL) was added catalytic amount of acetic acid (0.1 mL). The reaction mixture was refluxed for 3-4 h. Progress of the reaction was monitored by thin layer chromatography. Upon completion, the reaction mixture was cooled, and solid mass so obtained was filtered and recrystallized to afford pure bis(indolyl)hydrazide-hydrazones 5a-n in good yields.
