Adding a certain compound to certain chemical reactions, such as: 939-79-7, name is 4-Methyl-3-nitrobenzonitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 939-79-7, Product Details of 939-79-7
Synthesis of 6-cyano-lH-indole-2-carboxylic acid and 6-carbamoyl-lH-indole-2- carboxylic acid; Treat a suspension of 4-methyl-3-nitro-benzonitrile (2.11 g, 12.5 mmol) and oxalic acid ethyl ester propyl ester (2.99 g, 18.7 mmol) in EtOH (80 mL) with NaOEt (21% w/w, 18.2 mL). Stir the mixture at 40C overnight. Quench the reaction with water and acidify with 1 M HC1 solution. Concentrate to a residue and partition between EtOAc and water.Concentrate the organic layer and purify by silica gel chromatography to give the desired product 3-(4-cyano-2-nitro-phenyl)-2-oxo-propionic acid ethyl ester (3:1 keto/enol mixture) as a solid in 37% yield (1.21 g, 4.62 mmol).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Methyl-3-nitrobenzonitrile, other downstream synthetic routes, hurry up and to see.
