Reaction Steps
A mixture of 2-bromo-5-methoxybenzoic acid (141.5 g, 0.61 mol), 5-amino-1-ethylpyrazole (68 g, 0.61 mol), K2CO3 (84.2 g, 0.61 mol), DMF (500 ml) and Cu(OAc)2 (3 g) is refluxed for about 2 days. The reaction mixture is cooled and then is poured into water (1500 ml). The mixture is acidified with acetic acid, and the resulting solid is collected by filtration and dried to afford 110 g of N-(1-ethylpyrazol-5-yl)-5-methoxyanthranilic acid.
