실험 절차
A mixture of methyl 5-amino-2,4-dimethylbenzoate (1.2 g, 6.70 mmol, 1.00 equiv) and sodium hydroxide (1.5 g, 37.50 mmol, 5.60 equiv) in methanol/H2O (20/20 mL) was stirred overnight at 50° C. After cooling to ambient temperature, the organic phase was removed under reduced pressure. The pH of the remaining aqueous layer was adjusted to ˜4-5 with hydrogen chloride (aq., 2 M). The resulting solids were collected by filtration and dried to yield 1.0 g of a yellow solid.
