Vorschrift

A mixture of cis-4-chloro-5-iodo-7-[4-(4-methylpiperazino)cyclohexyl]-7H-pyrrolo[2,3-d]pyrimidine (1.0 g, 2.18 mmol), N1-phenyl -2-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]acetamide (0.81 g, 2.40 mmol), tetrakis(triphenyl-phosphine)palladium (70 mg, 0.131 mmol) and sodium carbonate monohydrate (0.65 g, 2.40 mmol) in ethylene glycol dimethyl ether (16 mL) and water (8 mL) was heated at 85° C. under an atmosphere of nitrogen for 18 hours. The mixture was cooled to ambient temperature and the solvent was removed under reduced pressure. The residue was purified by flash chromatography on silica using dichloromethane/methanol (9:1) as an eluent to give N1-phenyl-2-(4-{4-chloro-7-[4-(4-methylpiperazino)cyclohexyl]-7H-pyrrolo[2,3-d]pyrimidine-5-yl}phenyl)acetamide (0.74 g, 62%): 1H NMR (DMSO-d6, 400 MHz) 10.20(s, 1H), 8.66(s, 1H), 7.81(s, 1H), 7.62(d, 2H), 7.52(d, 2H), 7.41(d, 2H), 7.31(t, 2H), 7.04(t, 1H), 4.83(m, 1H), 3.70(s, 2H)<2.05-2.5(m, 13H), 2.17(s, 3H), 1.59-1.77(m, 4H); RP-HPLC (Hypersil HS C18, 5 m, 100 A, 250×4.6 mm; 25%-100% acetontrile over 10 min, 1 mL/min) tr 8.23 min.; MS:MH+ 543.2.
