Reaction Steps

To a solution of 5-bromo-3-[1-(ethylsulfonyl)-4-piperidinyl]-1H-indole-7-carboxamide (20.0 mg, 0.048 mmol), K3PO4 (21.0 mg, 0.096 mmol) and [4-(hydroxymethyl)phenyl]boronic acid (30.0 mg, 0.193 mmol) in dioxane/H2O (2 mL/0.7 mL) was bubbled argon for 5 minutes prior to addition of Pd(PPh3)4 (5.0 mg, 0.0048 mmol). The reaction mixture was heated in a microwave reactor (Smith synthesizer) for 20 minutes at 160° C. The solvent was evaporated, and the residue was partitioned between ethyl acetate and water. The organic layer was washed with brine (10 mL), dried over MgSO4, filtered, concentrated, and purified by reverse phase HPLC method A (water/CH3CN, 0.1% TFA 10-90%) to give the title compound (6.4 mg, 30%).
