Sodium Hydroxide → Racemic 3-{4-[1-(4'-trifluoromethyl-biphenyl-4-yloxy)-propyl]-benzoylamino}-propionic acid

Participants

Reaction Steps

To a mixture of 3-{4-[1-(4′-Trifluoromethyl-biphenyl-4-yloxy)-propyl]-benzoylamino}-propionic acid methyl ester (60 mg, 0.12 mmol) in methanol (2 mL) is added sodium hydroxide (5 N aqueous, 0.5 mL) and stirred for 5 hours. The reaction mixture is concentrated and acidified by 5 N HCl (0.5 mL), extracted with ethyl acetate. Combined organic layers are washed with water and brine, dried over sodium sulfate. Concentration gives the title compound (54 mg). MS (ES): 472.2 [M+H]+.
