Reaction Steps
The 5-(2-fluoro-ethoxy)-pyridine-2-carboxylic acid was prepared in a reaction sequence analogous to that in example 60 for the preparation of the 5-cyclopropylmethoxy-pyridine-2-carboxylic acid: Alkylation of the 5-hydroxy-pyridine-2-carboxylic acid methyl ester with 1-bromo-2-fluoroethane and hydrolysis of the 5-(2-fluoro-ethoxy)-pyridine-2-carboxylic acid methyl ester yielded the 5-(2-fluoro-ethoxy)-pyridine-2-carboxylic acid as a white solid. Mass (calculated) C8H8FNO3 [185.153]; (found) [M+H]+=186.
