In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 4983-28-2, name is 2-Chloro-5-hydroxypyrimidine, the common compound, a new synthetic route is introduced below. Recommanded Product: 2-Chloro-5-hydroxypyrimidine
Preparation Example 15 A mixture of 2-chloro-5-hydroxypyrimidine (487 mg) and 1-(3,5-dimethoxyphenyl)ethanol (680 mg), tributylphosphine (1.37 mL), and tetrahydrofuran (14 mL) was ice cooled, and 1,1′-(azodicarbonyl)dipiperidine (1.4 g) was added thereto followed by stirring at room temperature for 12 hours and stirring at 50° C. for 3 hours. Insoluble materials were removed by filtration and the filtrate was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give 2-chloro-5-[1-(3,5-dimethoxyphenyl)ethoxy]pyrimidine (415 mg).
The synthetic route of 4983-28-2 has been constantly updated, and we look forward to future research findings.
