Procedure
To 1-Benzyl-4-(2-methylphenyl)pyrrolidine-3-carboxylate (0.685 g, 2.214 mmol) in THF/MeOH/H2O (5 ml) was added 2N NaOH (3.32 ml, 6.64 mmol). The solution was stirred for 12 hours at room temperature and was acidified to pH1-2 with 1N HCl. The crude acid was extracted three times with EtOAc. The combined organic layers were dried over Na2SO4 and concentrated.
