Reaction Conditions:
with acetic acid at 100; for 3 h;
Steps:
5 Example 5
4-Bromophthalic anhydride (450 mg, 2.0 mmol) and 4-aminobutyric acid (206 mg, 2.0 mmol) were added to glacial acetic acid (10 mL) and heated to 100 ° C for 3 h.The reaction was quenched with water (10 mL), and the pH of the solution was adjusted by NaOH solution (0.1 mol/L).It is 6-8. Dichloromethane extraction (10 mL × 3), washed with saturated NaHCO3 solution, washed with waterAfter drying, it has a yellow solid of 600 mg.LC-MS and 1H-NMR confirmed the expected intermediate compound in a yield of 96.7%.
