19745-07-4, 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. 19745-07-4, name is 2,5-Dichloropyrazine, A new synthetic method of this compound is introduced below.
2-(4-Benzyloxyphenyl)-5-(6-octyloxypyridin-3-yl)pyrazine STR50 Step 1 In accordance with scheme C-I, 30 g (201 mmol) of 2,5-dichloropyrazine and 45.92 g (201 mmol) of 4-benzyloxyphenylboronic acid are coupled analogously to Example 4a to give 2-chloro-5-(4-benzyloxyphenyl)pyrazine.
