Synthetic Route of 73406-50-5 ,Some common heterocyclic compound, 73406-50-5, molecular formula is C8H9NO3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
Step 2 A mixture of ethyl 3-hydroxypicolinate (15 g, 900 mmol), tributylsilyl chloride (16.23 g, 110 mmol), imidazole (8.0 g, 120 mmol) in methylene chloride was stirred overnight under a nitrogen atmosphere. Water was added and the methylene chloride layer was separated and concentrated in vacuo. Purification on a silica gel column using ethyl acetate-hexane (1:4) as the eluant gave ethyl 3-(tributylsilyloxy)picolinate as a solid (20 g).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 73406-50-5, Ethyl 3-hydroxypicolinate, other downstream synthetic routes, hurry up and to see.
