Adding a certain compound to certain chemical reactions, such as: 5604-46-6, 2-Amino-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, Formula: C5H3Cl2N3O, blongs to pyrimidines compound. Formula: C5H3Cl2N3O
To a mixture of 112a (253 mg, 1.1 mmol) and 112b (192 mg, 1.0 mmol) was added DMF (20 ml) and the reaction mixture was stirred at room temperature overnight. Then poured the mixyure into ice/saturated sodium bicarbonate solution (40 ml). The precipitated solid was collected by filtration and washed with water. The solid was taken in DMF (10 ml) and added gl. acetic acid (10 drops). The reaction mixture was stirred at room temperature overnight and processed as above. The solid thus obtained (223 mg) was taken in dichloromethane (10 ml) and treated with DDQ (138 mg, 0.6 mmol) at room temperature for 1 hr. The reaction mixture was diluted with chloroform (30 ml) and washed with saturated sodium bicarbonate solution (50 ml). Separated the organic layer, and the aqueous layer was extracted with EtOAc (50 ml). Combined the organic layers, dried (Na2SO4), filtered and concentrated to provide 112c which was taken further without any purification.
The synthetic route of 5604-46-6 has been constantly updated, and we look forward to future research findings.
