Procedure

To a solution of 2-{3-[6-(2-methoxy-phenyl)-pyrimidin-4-yl]-ureido}-2-methyl-propionic acid ethyl ester (LVI) (370 mg, 1.03 mmol) in a mixture of THF and water (1:1) was added a solution of LiOH (87.0 mg, 2.06 mmol) in water at ice bath temperature over 10 min and then allowed to stir for two hours at room temperature. THF was evaporated and the aqueous solution was acidified with 2N HCl. This aqueous phase was then extracted with ethyl acetate (2×100 ml), the combined organic phases were washed with water and brine, dried over anhydrous sodium sulfate and concentrated in a vacuum rotavapor to afford 2-{3-[6-(2-methoxy-phenyl)-pyrimidin-4-yl]-ureido}-2-methyl-propionic acid as a white solid. Yield: 235 mg, 69.1%.
