Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 1193-24-4, name is 4,6-Dihydroxypyrimidine. A new synthetic method of this compound is introduced below., 1193-24-4
EXAMPLE 12 4,6-Dihydroxypyrimidine (0.5 g, 4.46 mmol) was suspended in chlorobenzene (10 ml) and dichlorotriphenylphosphorane (1.44 g, 4.46 mmol; previously prepared by the reaction of triphenylphosphine oxide with phosgene) was added as a solid. The mixture was stirred at 80 C. to 90 C. under a nitrogen atmosphere. Analysis by thin layer chromatography (tlc) of a sample removed after 90 minutes showed some 4,6-dichloropyrimidine formation. However, quite a lot of 4,6-dihydroxypyrimidine remained out of solution. Another quantity of dichlorotriphenylphosphorane (1.44 g, 4.46 mmol) was added and stirring continued for a further hour at 110 C. A cloudy yellow solution was obtained with a solid residue. Analysis by tlc confirmed the formation of 4,6-dichloropyrimidine.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,1193-24-4, 4,6-Dihydroxypyrimidine, and friends who are interested can also refer to it.
