A mixture of 2-bromo-2-(4-fluorophenyl)acetic acid (500 mg, 2.15 mmol) and 3-fluoroaniline (477 mg, 4.29 mmol) in acetonitrile (8 mL) is heated under microwave irradiation at 100° C. for 50 minutes. Then 3-fluoroaniline (238 mg, 2.15 mmol) is added again and reaction is heated at 120° C. for 45 minutes in a microwave oven (LC-MS monitoring: complete conversion). The organic solution is diluted with EtOAc and washed with 2N HCl and then with brine. The organic phase is dried over Na2SO4, filtered and the solvent is evaporated to give intermediate I131 as a white solid (510 mg, 90% yield).
