On August 31, 1988, Hiremath, Shivayogi P.; Ullagaddi, Ashok; Sekhar, K. Raja; Purohit, Muralidhar G. published an article.Application of 75629-62-8 The title of the article was Synthesis of various pyrazole-1-carbonylindoles. And the article contained the following:

2-Indolecarbohydrazides were treated with MeCOCH2CO2Et to give pyrazolinones I (R1 = H, Me; R2 = OMe, Me, Cl, Br H, OEt; R3 = H Me; R4 = Me, Ph, H). Pyrazoles II were prepared from hydrazides and MeCOCH2COMe. The experimental process involved the reaction of 2-((1H-Indol-3-yl)methylene)malononitrile(cas: 75629-62-8).Application of 75629-62-8
