To a solution of 1-(3-benzylquinolin-2-yl)-2-methylpropan-1-ol 13 (102 mg, 1 eq.) in dry tetrahydrofuran (3 ml) at 0° C., was added phthalimide (154 mg, 3 eq), triphenylphosphine (138 mg, 1.5 eq.), and DIAD (1.5 eq., 104 μl). The reaction was allowed to warm to room temperature and stirred overnight. The solvent was evaporated. The residue was dissolved in ethyl acetate. The organic layer was washed with saturated sodium bicarbonate, saturated sodium chloride, dried over magnesium sulfate, filtered and concentrated. The material was purified by flash chromatography to yield 91 mg of 2-[1-(3-benzylquinolin-2-yl)-2-methylpropyl]-1H-isoindole-1,3(2H)-dione 14 as yellow oil.
