With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.1753-48-6, name is 2-Aminopyrimidine-5-carbonitrile, molecular formula is C5H4N4, molecular weight is 120.1121, as common compound, the synthetic route is as follows.category: pyrimidines
A stirred mixture of commercially available 2-amino-5-cyano-pyrimidine [CAS-No. 1753-48-6] (1.39 g, 11.6 mmol), hydroxylamine hydrochloride (1.61 g, 23.2 mol) and potassium carbonate (4.8 g, 34.7 mol) in ethanol (57 mL) was heated under reflux conditions for 3 h. The reaction mixture was evaporated and purified by column chromatography on silica gel (dichloromethane/MeOH 9:1) to yield the title compound (1.28 g, 72%) as an off-white solid. MS (EI) 153.1 [(M)+]; mp 218 C.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,1753-48-6, 2-Aminopyrimidine-5-carbonitrile, and friends who are interested can also refer to it.
