Reference of 36070-80-1, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 36070-80-1 as follows.
General procedure: The corresponding substituted salicylanilide 2 (1 mmol) and 5-chloropyrazine-2-carboxylic acid 1 (1 mmol) were dissolved in dryDMF (8 mL), the solution was cooled to 10 C and DCC (1.2 mmol)was added in three portions during 1 h. The mixture was stirred foradditional 3 h at the same temperature and then stored at 4 C for20 h. The precipitate of N,N0-dicyclohexylurea was removed byfiltration and the solvent was evaporated in vacuo till dryness. Thecrude products 3 were purified by one or repeated crystallizationfrom ethyl acetateehexane mixture.
According to the analysis of related databases, 36070-80-1, the application of this compound in the production field has become more and more popular.
