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 31230-17-8 as follows. SDS of cas: 31230-17-8<\/a><\/p>\n

A mixture of 2,4-dichloropyrimidine (0.967 g, 6.49 mmol), 3-amino-5-methylpyrazole (0.63 g, 6.40 mmol), and ethyldiisopropylamine (2.8 mL, 16.22 mmol) in ethanol (13 mL) was stirred at -10C for 2 h, then at r.t. overnight, and finally at 50C for 3.5 h. The mixture was concentrated to a total volume of approximately 10 mL. Upon repeated addition of diethylether, (2-chloropyrimidin-4-yl)-(5-methylpyrazol-3-yl)amine (0.258 g, 1.23 mmol, 19 %) was obtained as colourless crystals. LC\/ESI-MS: m\/z = 210 [M(35Cl) +H]+; m\/z = 208 [M(35Cl)-H]-; Rt = 2.30 min.<\/p>\n
