Reaction Steps

To 20 ml DMF is added valine (1.17 g, 10 mmol) and potassium carbonate (5.5 g, 40 mmol) followed by α,α-dibromo-o-xylene (2.63 g, 10 mmol). The reaction mixture is stirred for about 20 hours at RT under nitrogen and then poured into ether and water. The aqueous layer is separated, acidified to about pH 3 with aqueous HCl and extracted thoroughly with ether. The organic layer is washed with water and brine, dried and solvent removed under vacuum to give 2-(2-isoindolinyl)-3-methylbutanoic acid.
