Procedure

To a solution of 5-fluoro-2-(2-iodo-3-methyl-benzoylamino)-indan-2-carboxylic acid ethyl ester (400 mg, 0.85 mmol) and cyclopenten-1-ylboronic acid (383 mg, 3.42 mmol) in EtOH (10 mL) and dioxane (5 mL) is added palladium anchored homogeneous catalyst, FibreCatPd(0) (4.84% Pd, 186 mg, 8.5% mmol) and 2M aqueous solution of K2SO4 (1.71 mL, 3.42 mmol). The resulting reaction mixture is covered with argon and run in a microwave reaction: 110° C., 8 h. After concentration in vacuo, the residue is purified HPLC to give a pure product (151) as white solid (240 mg, 69%).
