Reaction Steps

6-Bromo-2-(1-methyl-1H-pyrazol-4-yl)-1H-pyrrolo[3,2-c]pyridine (Preparation 22, 27 mg 0.10 mmole) and 2-bromopyridine (24 mg, 15 uL, 0.15 mmole) were dissolved in DMA (0.7 ml) and potassium carbonate (20 mg, 0.14 mmole) and copper(I) iodide (4.0 mg, 0.022 mmole) were added. The reaction was placed under argon and heated by microwave at 180° C. for 60 minutes followed by 210° C. for 45 minutes. The reaction was taken up in ethyl acetate (25 mL) and the solution washed with water (3×7 mL) and brine. The aqueous solutions were backwashed with a single portion of ethyl acetate. The combined organic layers were dried (MgSO4) and concentrated in vacuo. The residue was purified using preparative TLC eluting with ethyl acetate to afford the title compound 17 mg (48%). 1H-NMR (CDCl3, 500 MHz): 3.88 (s, 3H), 6.72 (d, J=0.95 Hz, 1H), 7.18 (d of t, J=0.95, 7.88 Hz, 1H), 7.24 (s, 1H), 7.26 (d, J=0.63 Hz, 1H), 7.44 (ddd, J=0.95, 4.73, 7.57 Hz, 1H), 7.51 (t, J=0.95 Hz, 1H), 7.86 (t of d, J=1.89, 7.57 Hz, 1H), 8.66 (d, J=0.95 Hz, 1H), 8.73 (ddd, J=0.95, 1.89, 4.73 Hz, 1H).
