Procedure

To a solution of N-(2-acetylamino-indan-5-yl)-2-bromo-benzamide (the title C compound; 0.150 g, 0.40 mmol) and 4-fluorobenzeneboronic acid (0.0.84 g, 0.60 mmol) in DME (7 mL) is added PdCl2(dppf) (0.010 g, 0.012 mmol) followed by K3PO4 (0.25 g, 1.20 mmol). The reaction mixture is degassed and heated at reflux under N2 atmosphere for 16 h. After cooling to room temperature, the reaction mixture is diluted with water and extracted with ethyl acetate. The organic layer is dried (MgSO4) and concentrated under reduced pressure to give a tan solid. Trituration with ethyl acetate gives 4′-fluorobiphenyl-2-carboxylic acid (2-acetylamino-indan-5-yl)-amide as a grey solid, mp 218-220° C. MS (ES+), m/z 389 (M+1).
