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. 1450-93-7, name is 1H-imidazol-2-amine sulfate(2:1), A new synthetic method of this compound is introduced below., Formula: C6H12N6O4S
EXAMPLE 2 5-(4-Pyridyl)imidazo[1,2-a]pyrimidine A mixture of 5.29 g of 2-aminoimidazole hemisulfate, 3.28 g of anhydrous sodium acetate and 7.04 g of 3-dimethylamino-1-(4-pyridyl)-2-propen-1-one (prepared according to the procedure of Example 63 in U.S. Pat. No. 4,281,000) in 100 ml of glacial acetic acid was heated under reflux for 16 hours. The procedure of the above Example 1 was followed and the title compound was obtained as pale yellow needles, mp 244-245 C.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
