Procedure

Step 14B [9058-121-2]: 3-Methyl-2-[4′-(quinolin-2-yloxy)-biphenyl-4-sulfonylamino]-butyric acid tert-butyl ester (164 mg) was dissolved in dichloroethane (12 mL) and hydrolyzed with TFA (4 mL) at room temperature over a period of 4 hrs. Solvent was removed and crude was purified by column chromatography (Eluent 10% MeOH/DCE) to afford 3-Methyl-2-[4′-(quinolin-2-yloxy)-biphenyl-4-sulfonylamino]-butyric acid in 58% yield (84.8 mg).
