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.
2-(Pyrrolidin-1-yl)carbonyl-3-hydroxy pyridine 18 g (0.093 moles) of ethyl-3-hydroxypicolinate [J. Heterocyclic Chem. 23 , 665, 1986] were cooled at -5C and ml 250 of pyrrolidine were added under nitrogen atmosphere. After the addition, the solution was allowed to reach room temperature, stirred 24 h and then evaporated in vacuo to give 15 g of the title compound as a slight yellow oil which crystallized on standing.
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.
