Analyzing the synthesis route of 1-(4,6-Dichloropyrimidin-5-yl)ethanone

At the same time, in my other blogs, there are other synthetic methods of this type of compound,60025-06-1, 1-(4,6-Dichloropyrimidin-5-yl)ethanone, and friends who are interested can also refer to it.

Adding a certain compound to certain chemical reactions, such as: 60025-06-1, 1-(4,6-Dichloropyrimidin-5-yl)ethanone, 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, category: pyrimidines, blongs to pyrimidines compound. category: pyrimidines

Synthesis of Compound 6.1. Hydrazine hydrate (107 uL, 2.20 mmol) was slowly added to a solution of 1-(4,6-dichloro-pyrimidin-5-yl)-ethanone (Clark, J. et al J. Chem. Soc. 1976, 9, 1004) (400 mg, 2.09 mmol) and triethylamine (280 uL, 2.0 mmol) in 1,4-dioxane (7 mL) at 8 C. After the addition was complete, the reaction mixture was warmed to RT. After 2.5 hr, the reaction mixture was filtered through celite and then evaporated to afford compound 6.1 (200 mg) as a yellow solid. 1H-NMR (400.13 MHz, DMSO-d6) 14.07 (s, 1H), 8.75 (s, 1H), 2.64 (s, 3H). MS m/z 169 [M+1]+.
