Procedure

To a solution of 2-iodo-3-methyl-benzoic acid (3.85 g, 14.7 mmol), 2-amino-5-fluoro-indan-2-carboxylic acid ethyl ester (3.00 g, 13.4 mmol), HATU (6.10 g, 16.1 mmol) in anhydrous DMF (6 mL) is added DIPEA (3.30 mL, 20.1 mmol). The resulting solution is stirred at RT overnight. After the removal of DMF in vacuo, the residue is recrystallized from EtOAc to give a pure product (147) as white solid (3.90 g, 62%).
