Participants

Reaction Steps

37 mg (80 μmol) of methyl 2(S)-ethoxy-3-{4-[5-(3-heptyl-1-methylureido)-2-methyl-2H-[1,2,4]triazol-3-yl]phenyl}propanoate placed in 2 ml of tetrahydrofuran and 0.1 ml (0.1 mmol) of aqueous 1M lithium hydroxide solution are stirred at room temperature overnight. The reaction medium is acidified to pH 4 and extracted with ethyl acetate. The organic phase is washed with water, with saturated sodium chloride solution, dried over magnesium sulfate, filtered and evaporated. 30 mg (83%) of 2(S)-ethoxy-3-{4-[5-(3-heptyl-1-methylureido)-2-methyl-2H-[1,2,4]-triazol-3-yl]phenyl}propanoic acid are obtained in the form of a white solid.
