Methanol → 3-Methyl-2-[4'-(3-methyl-quinolin-2-yloxymethyl)-biphenyl-4-sulfonylamino]-butyric acid

Participants

Reaction Steps

3-Methyl-2-[4′-(3-methyl-quinolin-2-yloxymethyl)-biphenyl-4-sulfonylamino]-butyric acid methyl ester (203 mg, 0.39 mmol, 1 equiv.) was dissolved in THF (8 mL) and MeOH (4 mL) and hydrolyzed with IN NaOH (5.83 mL, 5.83 mmol, 13 equiv.). After stirring for 3 days, solvent was removed and the residue was dissolved in H2O. The mixture was then acidified to pH 3 using 1N HCl. Solid precipitated from the mixture was collected by filtration and washed with water. After drying in vacuum oven, 101 mg of 3-Methyl-2-[4′-(3-methyl-quinolin-2-yloxymethyl)-biphenyl-4-sulfonylamino]-butyric acid was obtained in 76.3% yield.
