Procedure

1.44 ml (1.45 mmol, 5 eq) of lithium hydroxide are added to a solution of 111 mg (0.29 mmol, 1 eq) of methyl 3-{5-[3-(1-methyl-3-pentylureido)phenyl]pyrimidin-2-yl}propanoate in 3 mL of tetrahydrofuran. The reaction mixture is stirred for four hours at room temperature. The reaction is stopped by adding 10 ml of water, washed with ether and then acidified with 1N hydrochloric acid solution, and then extracted with ethyl acetate. The organic phases are combined and dried over sodium sulfate. The solvents are evaporated off and the residue is then crystallized from ether. 66.7 mg of 3-{5-[3-(1-methyl-3-pentylureido)phenyl]pyrimidin-2-yl}propanoic acid are obtained in the form of white crystals. Yield=48%.
