A solution of methyl 4-amino-5-iodo-2-methoxybenzoate (intermediate 128; 5 g, 16.28 mmol) and dicyanozinc (1.5 g, 12.77 mmol) in dimethylformamide (50 mL) in a slenck vessel was degasified with nitrogen. Then tetrakis (1 g, 0.87 mmol) was added and the reaction mixture was stirred at 80° C. for 2 hours. Water was added into the reaction mixture and the crude was extracted with ethyl acetate, the organic layer was washed with brine, dried and the solvent was removed under reduced pressure. The crude obtained was treated with methanol and ether to obtain the title compound as a yellow solid (76%).
