Hydrochloric Acid → 3-(1-Oxo-1,3-dihydro-isoindole-2-yl)-3-phenyl-propionic acid

Participants

Reaction Steps

3-(1-Oxo-1,3-dihydro-isoindole-2-yl)-3-phenyl-propionic acid methyl ester (0.5 mmol, 1 eq) is dissolved in 8 mL 1 M NaOH/MeOH (25% V/V) and stirred at room temperature for 2 h. The solution is acidified with 1 M HCl and extracted with dichloromethane. The organic phase is dried over Na2SO4, filtered and concentrated in vacuo. 3-(1-Oxo-1,3-dihydro-isoindole-2-yl)-3-phenyl-propionic acid is obtained as red-orange residue (81% yield); ES-MS (MH+)=282.2.
