As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 4595-61-3, name is Pyrimidine-5-carboxylic acid, molecular formula is C5H4N2O2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. Product Details of 4595-61-3
1,1?-carbonyldiimidazole (1.23 g, 7.57 mmol) was added to a suspension of pyrimidine-5-carboxylic acid (783 mg, 6.31 mmol) in DCM (20 mL) and the mixture was stirred at room temperature for 15 min before addition of N,O-dimethylhydroxylamine hydrochloride (739 mg, 7.57 mmol). The mixture was stirred at room temperature for 5 d, then was diluted with saturated aqueous NH4Cl and water and extracted with DCM. The organic phase was washed with water, and the aqueous phases were back-extracted with DCM. The organic phase was dried (Na2SO4), filtered, and concentrated, affording the crude title compound as a light yellow oil which was used without further purification in the next reaction
With the rapid development of chemical substances, we look forward to future research findings about 4595-61-3.
