実験手順
A mixture of N-(6-amino-5-bromo(2-pyridyl))(2-fluorophenyl)carboxamide (61) (16 mg, 0.05 mmol), bis(ditertbutyl(4-dimethylaminophenyl)phosphine)dichloropalladium (II) (4 mg, 10% mol) and K3PO4 (11 mg, 0.05 mmol) in 0.5 ml ACN, 0.5 ml dioxane, 0.2 ml H2O was bubbled with argon before heated at 85° C. for 4 h. After cooling down to r.t., the reaction mixture was taken up in EA, washed with aq. NaHCO3 and brine. Org. phase was dried over Na2SO4, concentrated to dryness. Flash silica gel column purification (0-90% B, A: hexane; B: 50% EA in hexane) furnished 2.2 mg crude desired product as yellow solid which was re-purified on prep HPLC to give 0.8 mg N-[6-amino-5-(1-methyl-3-phenylpyrazol-5-yl)(2-pyridyl)](2-fluorophenyl)carboxamide (69) as off-white solid. (yield: 4%, purity>90%).
