Versuchsvorschrift

A mixture of {6-Oxo-1-propyl-8-[1-(3-trifluoromethyl-benzyl)-1H-pyrazol-4-yl]-6,7-dihydro-1H-purin-2-ylamino}-acetic acid ethyl ester in THF (2 ml), MeOH (1 ml) and Water (1 ml) was added lithium hydroxide (0.02 g, 0.476 mmol) at 0° C. The reaction mixture was stirred at room temperature for overnight. The reaction mixture was concentrated and water was added. It was extracted with ethyl acetate. Ethyl acetate layer was washed with water and brine. Ethyl acetate layer was dried over sodium sulphate, filtered and concentrated under reduced pressure and the residue obtained was purified by column chromatography to obtain {6-Oxo-1-propyl-8-[1-(3-trifluoromethyl-benzyl)-1H-pyrazol-4-yl]-6,7-dihydro-1H-purin-2-ylamino}-acetic acid (0.035 g, 46%) as a yellow solid.
