Procedure

A 20 ml sealable vial was charged with 3-[1-(2,6-Dichloro-3-fluorophenyl)ethyl]-5-(4,4,5,5-tetramethyl[1,3,2]dioxaborolan-2-yl)-1H-pyrrolo[2,3-b]pyridine (80.0 mg, 0.156 mmol), 4-(4-Iodopyrazol-1-yl)cyclohexanone (52.5 mg, 0.172 mmol), Pd(PPh3)4 (12.0 mg, 0.0103 mmol), potassium carbonate (71.8 mg, 0.514 mmol), and 4:1 dioxane:water (5 mL). The cap was sealed and the vial was evacuated and backfilled with nitrogen (3×). After that, the vial was heated at 90° C. for 2 h. The reaction mixture was partitioned between EtOAc/H2O (15 ml/10 ml). The aqueous phase was extracted with EtOAc (10 ml). The combined organic extracts were washed with water (10 ml) and brine (10 ml), dried over MgSO4, filtered, and concentrated in vacuo to give a brown oil that was purified by prep. TLC eluting with 4% MeOH/DCM to give the title compound. 1H NMR (400 MHz, CDCl3): δ=1.88 (d, J=7.2 Hz, 3H), 2.31-2.68 (m, 8 H), 4.64 (tt, J=11.8, 4.0 Hz, 1 H), 5.28 (q, J=7.2 Hz, 1 H), 7.01 (dd, J=8.0 & 8.8 Hz, 1 H), 7.30 (s, 1 H), 7.32 (brs, 1 H), 7.48 (s, 1 H), 7.60 (d, J=0.8 Hz, 1 H), 7.66 (d, J=0.8 Hz, 1 H), 8.41 (brs, 1 H), 9.77 (brs, 1 H). MS (ES+): m/z=471.16/473.11 (100/68) [MH+]. HPLC: tR=3.39 min (polar—5 min, ZQ3).
