A mixture of 3.96 g (9.4 mMol) of 4-[4-chloro-1-(4-methoxy-benzyl)-1H-pyrrolo[2,3-d]pyrimidin-6-yl]-benzoic acid ethyl ester, 2.14 g (13 mMol) of 4-fluoro-5-hydroxy-2-methyl-1H-indole (preparation see WO 00/47212; Ex. 237) and 2.44 (17.7 mMol) of K2CO3 in 90 ml of DMF is heated for 9 h at 95° C. The reaction mixture is concentrated in vacuuo, the residue dissolved in EtOAc and water, the aqueous layer separated off and extracted twice with EtOAc. The organic layers are washed with water and brine, dried (Na2SO4) and concentrated. Column chromatography (SiO2, EtOAc/hexane 1:1) gives the title compound; TLC (EtOAc/hexane 1:1) Rf=0.24; MS-ES+: (M+H)+=551.
