실험 절차

A mixture of 3-hydroxyphthalic anhydride (543 mg, 3.31 mmol), 4-methoxybenzylamine (0.43 mL, 3.31 mmol) and acetic acid (3 mL) was heated at 100° C. for 4 hours. The mixture was allowed to cool and diluted with water (20 mL). The white solid was collected by filtration, washed well with water and dried to give the title compound (760 mg, 81%). 1H NMR (DMSO-d6) 11.03 (1H, s), 7.61 (1H, dd), 7.28 (1H, d), 7.23-7.19 (3H, m), 6.89-6.86 (2H, m), 4.63 (2H, s), 3.71 (3H, s). MS: [M−H+] 282.
