Procedure

In a vial were placed methyl 6-cyano-7-(4-(3-iodophenylcarbamoyl)phenoxy)chroman-4-carboxylate (Preparation 3) (56 mg, 0.1010 mmol), p-tolylboronic acid (17.855 mg, 0.1313 mmol), Na2CO3 (32.121 mg, 0.3030 mmol), toluene (1 ml), and water (0.1 ml). The mixture was degassed with Argon for few minutes. Tetrakis(triphenylphosphine)palladium(0) (5.836 mg, 0.005 mmol) was added and the vial was sealed. The mixture was stirred at 100° C. for 24 hours. The crude mixture was purified on silica gel (EtOAc in hexanes gradient) to provide 33.1 mg of the title compound as foamy solid (63%).
