Yield:40101-51-7 94.3%
Reaction Conditions:
with acetic acid at 100; for 3 h;
Steps:
18 Example 18
Add phthalic anhydride (450 mg, 3.0 mmol) and 3-aminobenzoic acid (415 mg, 3.0 mmol) to glacial acetic acid(10 mL), heated to 100 ° C for 3 h. The reaction was quenched with water (10 mL).The pH of the solution was adjusted to 6-8 by a NaOH solution (0.1 mol/L). Dichloromethane extraction (10mL × 3),Wash with saturated NaHCO3 solution, wash with water, and combine with organicAfter drying, 746 mg of a yellow solid was obtained.LC-MS and 1 H-NMR confirmed the expected intermediate compound in a yield of 94.3%.
