A mixture of ethyl 4-cyano-5-(2-(fluoromethyl)morpholino)-3-iodothiophene-2-carboxylate (288 mg, 0.000679 mol), 2,4-dichlorophenylboronic acid (262 mg, 0.00137 mol), tetrakis(triphenylphosphine)palladium(0) (51 mg, 0.000044 mol) and sodium carbonate (220 mg, 0.0021 mol) in water (3 mL, 0.1 mol) and 1,2-dimethoxyethane (10 mL, 0.1 mol) was flushed with argon and then irradiated in microwave at 140° C. for 12 min. The reaction mixture was filtered and concentrated in vacuum to afford ethyl 4-cyano-3-(2,4-dichlorophenyl)-5-(2-(fluoromethyl)morpholino)thiophene-2-carboxylate (300 mg, 99%). LCMS: (FA) ES+ 443.15.
