Reaction Steps

To a solution of ethyl 2-chloro-4-(3-fluoro-4-(1H-imidazol-1-yl)phenylamino)pyrimidine-5-carboxylate (383 mg, 1.06 mmol) in THF (5 mL), aq. 1N LiOH (2.00 mL, 2.00 mmol) was added. The mixture was stirred at room temperature overnight. THF was removed in vacuo. Upon acidification with 1N HCl, the mixture was purified by HPLC to give 2-chloro-4-(3-fluoro-4-(1H-imidazol-1-yl)phenylamino)pyrimidine-5-carboxylic acid (68 mg). MS 334.1 and 336.1 (M+H, Cl pattern)
