Synthetic Route of 871254-61-4, Adding some certain compound to certain chemical reactions, such as: 871254-61-4, name is 2,4-Dichloropyrimidine-5-carbaldehyde,molecular formula is C5H2Cl2N2O, 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 871254-61-4.
To a flask containing MeOH (24.0 mL), was added 2,4- dichloropyrimidine-5-carbaldehyde (1.5159 g, 1.0 equiv.), PPTS (215.0 mg, 0.1 equiv.) and trimethyl orthoformate (6.0 mL). The reaction mixture was stirred at 65 C for 14 h, cooled to rt and concentrated. The resulting residue was purified via column chromatography to yield the title compound as an oil (1.4361 g, 75% yield). NMR (400 MHz, Chloroform-^ d 8.73 (s, 1H), 5.54 (s, 1H), 3.38 (s, 7H). LC-MS: m/z 223, 225 [M+H]+.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 871254-61-4, 2,4-Dichloropyrimidine-5-carbaldehyde, other downstream synthetic routes, hurry up and to see.
