Procedure

To a mixture of 3-[7-(2-Methoxy-phenyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl]-benzoic acid (35 mg, 0.1 mmol), EDCI (77 mg, 0.40 mmol), HBTU (3.8 mg, 0.01 mmol) and diisopropylethylamine (175 μl, 1.0 mmol) in DMF (1 mL) was added 2-(dimethylamino)ethylpiperzine (55 μl, 0.3 mmol). The mixture was stirred at 70° C. for 5 hours before the solvents were removed. The resulting yellow oil was washed with water, dissolved in DMSO and purified on reverse phase HPLC to afford the title compound (8.6 mg, 12% over 2 steps) as yellow solid. MS: m/z 485.2 [MH+].
