Procedure

Phthalimide 35 (1.1 g, 2.8 mmol) was dissolved in a solution containing 6.6% methylamine in ethanol (100 mL) and allowed to stir at room temperature overnight. The solvent was removed under reduced pressure and the residue was purified by flash chromatotography (silica gel, chloroform/methanol/ammonium hydroxide, 10:1:0.1, v/v) to afford the free amine 36 (0.31 g, 42%) as a white powder. 1H NMR (300 MHz, CD3OD) δ 1.51 (m, 2H), 1.65 (m, 2H), 2.66 (m, 4H), 3.02 (m, 6H), 7.23 (d, 2H), 7.35 (d, 2H).
