Reaction Steps

To a solution of 5-(2,2,3,3-tetrafluoro-propoxy)-pyridine-2-carboxylic acid methyl ester (2.6 g) in THF (20 ml) and water (15 ml) was added lithium hydoxide solution (1 M, 19.4 ml) and the reaction mixture was stirred at 22° C. for 30 min. The reaction mixture was neutralised by addition of aqueous HCl (1 N, 19.4 ml), the organic solvent was evaporated, the suspension obtained still containing water was filtered and the residue was dried to give 5-(2,2,3,3-tetrafluoro-propoxy)-pyridine-2-carboxylic acid (2.3 g) as an off-white solid.
