Adding a certain compound to certain chemical reactions, such as: 5305-40-8, 4,6-Dichloropyrimidine-5-carbaldehyde, 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
Ammonia was bubbled through a solution of 4,6-dichloro-pyrimidine-5-carbaldehyde (1 g, 5.68 mmol) in toluene (100 mL) for 10 min and the solution was stirred at room temperature overnight. The yellow precipitate was filtered off, washed with EOAc and dried in vacuo to afford the pure product (880 mg, 99%). 1H NMR (DMSO-d6) delta 10.23 (s, 1H), 8.72 (br, 1H), 8.54 (br, 1H), 8.38 (s, 1H).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,5305-40-8, 4,6-Dichloropyrimidine-5-carbaldehyde, and friends who are interested can also refer to it.
