A mixture of 2-iodobenzoic acid (14 g, 0.057 mol), 5-amino-1-phenylmethylpyrazole (9.8 g, 0.057 mol), DMF (140 ml), potassium carbonate (8.3 g) and Cu(OAc)2 (0.1 g) is refluxed for about 2 days. The reaction mixture is poured into water, acidified with acetic acid to a pH of 5, and then the solid which forms is collected by filtration, washed with water, then ether and then is dried to afford N-(1-phenylmethylpyrazol-5-yl) anthranilic acid, m.p. 190° C.
