Application of 20090-69-1, Adding some certain compound to certain chemical reactions, such as: 20090-69-1, name is 2-Chloro-4-methylpyrimidin-5-amine,molecular formula is C5H6ClN3, 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 20090-69-1.

To a stirred solution of 2-chloro-4-methylpyrimidin-5-amine (2 g, 14.706 mmol, CAS RN20090-69-1) in DCM (50 mL) was added acetic anhydride (2.96 mL, 29.412 mmol) followed by triethyl amine (6.15 mL, 44.118 mmol) and reaction mixture was stirred at 25C for 16 h. After completion of the reaction, the mixture was evaporated.. The crude product was purified by chromatography over silica gel (23-26% EtOAc/n-hexane) to afford the compound as an offwhite solid (2.49 g, 91%). MS (ESI): mlz = 186.1 [M+H]+
