To a mixture of 2-amino-terephthalic acid (2.5 g, 23.8 mmol) and 1-iodo-4-methyl-benzene (7.78 g, 35.7 mmol) in butane-2,3-diol (38 mL) was added Cu (24 mg, 0.016 mmol), CuCl (950 mg, 9.6 mmol), and n-methyl morpholine (6.5 mL) under argon. The mixture was heated at 150° C. for 18 h. The reaction mixture was cooled to room temperature and HCl (0.1 N, 100 mL) was added. The resulting yellow precipitate was collected by filtration and triturated in a mixture of Et2O and EtOAc (1:1, 50 mL) for 1 h. The yellow solid was filtered, washed with ether (25 mL), and dried in vacuo to give 2.4 of 138A. HPLC retention time=3.046 min., condition A.
