Versuchsvorschrift

A mixture of phthalic anhydride (6.46 g, 43.6 mmol) and 5-aminopentanol (4.5 g, 43.6 mmol) was heated to 145° C. in an open flask for 30 min. A stream of N2 was applied to expel water vapor. After cooled to room temperature, the reaction residue was dried on vacuum pump. The product was obtained as colorless oil: yield 100%; 1H NMR (CDCl3) δ 1.4-1.5 (m, 2H), 1.6-1.8 (m, 4H), 3.6 (t, 2H, J=6.5), 3.7 (t, J=7.2 Hz), 7.7 (m, 2H), 7.8-7.9 (m, 2H).
