Reaction Steps

To stirred solution of Ethyl-6-(2-(5-fluoro-2-(((R)-tetrahydrofuran-3-yl)oxy)phenyl)pyrrolidin-1-yl)imidazo[1,2-a]pyridine-3-carboxylate (1.15 g, 26.18 mmol) in ethanol was added 1M LiOH (2.3 ml) solution and stirred for 5 h at 85° C. Solvent was removed under reduced pressure and residue was dissolved in water, extracted unwanted impurities with diethyl ether and water was acidified with 2N HCl and solid was collected by filtration. Solid was dried under high vacuum to afford 6-(2-(5-fluoro-2-(((R)-tetrahydrofuran-3-yl)oxy)phenyl)pyrrolidin-1-yl)imidazo[1,2-a]pyridine-3-carboxylic acid as pale yellow solid (400 mg, yield: 37.7%), MS (ESI): 412.1 (M+H).
