With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.15317-58-5,1H-Indole-3-carbohydrazide,as a common compound, the synthetic route is as follows.
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, As the paragraph descriping shows that 15317-58-5 is playing an increasingly important role.
