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. 26452-81-3, name is 4-Chloro-6-methoxypyrimidine. A new synthetic method of this compound is introduced below., Safety of 4-Chloro-6-methoxypyrimidine
Example 1 90 parts by weight of phosphorus oxychloride and 10 parts by weight of 4-chloro-6-methoxypyrimidine were introduced into a stirred vessel. The mixture was heated with stirring to 100° C. and, at this temperature, 6 parts by weight of water were metered in at a constant rate over the course of 4 hours. The mixture was then stirred at 100° C. for 1 hour. After cooling to room temperature, 99.6 parts by weight of a reaction mixture whose HPLC analysis showed contents of 0.2percent 4-chloro-6-methoxypyrimidine and 9.3 parts by weight of 4,6-dichloropyrimidine were obtained.
