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. 4349-07-9, name is 5-Iodopyrimidin-4-ol, the common compound, a new synthetic route is introduced below. category: pyrimidines
Method 0 Preparation of 4-Chloro-5-iodopyrimidine 5-Iodo-4(3H)-pyrimidinone (1 eq. ) was suspended in toluene to which was added POC13 (2.0 eq. ). The reaction mixture was heated to reflux for 3 hours, and then cooled and concentrated. The residue was suspended in water, adjusted to pH=7 by addition of 4N sodium hydroxide, and extracted with ethyl acetate. The organic extracts were washed with brine, dried (MgS04), filtered and stripped to give a red oil. The crude product was dissolved in methanol and silica gel was added. Following concentration, the coated silica gel was loaded onto a plug of silica gel and elution with ethyl acetate/hexanes yielded the title compound.
The synthetic route of 4349-07-9 has been constantly updated, and we look forward to future research findings.
