Procedure
18 g (0.093 moles) of ethyl-3-hydroxypicolinate [J. Heterocyclic Chem. 23, 665, 1986] were cooled at -5° C. 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.
