1.00 g (1.86 mmol) of N-[4-({3-bromo-1-[(4-methylphenyl)sulfonyl]-1H-pyrrolo[2,3-b]pyridin-4-yl}oxy)-3,5-difluorophenyl]acetamide, 1.12 g (13.1 mmol) of cyclopropylboronic acid (Wallace, Debra J.; Chen, Cheng-yi; Tetrahedron Lett. 2002, 43(39), 6987-6990), 52.3 mg (0.19 mmol) of tricyclohexylphosphine and 1.39 g (6.53 mmol) of potassium phosphate are suspended in 10 ml of toluene and 0.5 ml of water. The solution is degassed, and 20.9 mg (0.09 mmol) of palladium(II) acetate are added. The mixture is heated at 100° C. for 1.5 h. After cooling, ethyl acetate is added and the organic phase is separated off and washed twice with water. The organic phase is dried over sodium sulfate and concentrated. The product is purified by preparative HPLC.
