Procedure

To a microwave vial was added 5-bromo-2-[(phenylmethyl)oxy]-N-3-pyridinylbenzamide (may be prepared as described in example 2; 310 mg, 0.81 mmol), 1,1-dimethylethyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole-1-carboxylate (262 mg, 0.89 mmol), 1,4-dioxane (3 ml), sodium carbonate (1.62 ml, 1.62 mmol) and tetrakis(triphenylphosphine)palladium(0) (56.1 mg, 0.05 mmol). The vial was sealed and heated to 120° C. for 25 min under microwave conditions. The mixture was evaporated under reduced pressure and water (5 ml) was added to the residue. The mixture was extracted with ethyl acetate (3×10 ml). The organics were combined and evaporated under reduced pressure, and the residue was purified using the MDAP to yield the title compound. 44 mg.
