Procedure

A flask containing 4-aminophenethyl alcohol (1 g, 7.29 mmol), phthalic anhydride (1.13 g, 7.65 mmol) and acetic acid (6 mL) was heated at 100° C. for 1 h. The reaction mixture was poured into water (50 mL) and the solid was filtered off and washed with water. The crude was purified by flash column chromatography to afford the desired product as white solid (1.2 g, 62%). 1H NMR: 2.92 (t, 2H, J=6.6 Hz), 3.89 (t, 2H, J=6.6 Hz), 7.38 (s, 3H), 7.77-7.82 (m, 2H), 7.92-7.97 (m, 21-1).
