Procedure

To a microwave vial was added 5-bromo-2-[(phenylmethyl)oxy]-N-3-pyridinylbenzamide (may be prepared as described in example 2; 100 mg, 0.26 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (59.7 mg, 0.29 mmol), 1,2-dimethoxyethane (2 ml), 1M sodium carbonate (0.52 ml, 0.52 mmol) and tetrakis(triphenylphosphine)palladium(0) (18.09 mg, 0.02 mmol). The vial was sealed and heated to 120° C. for 25 min under microwave conditions. The mixture was evaporated under reduced pressure. Water (5 ml) was added to the residue and the mixture was extracted with ethyl acetate (3×10 ml). The organics were combined and evaporated and the residue was purified using MDAP to yield the title compound. 31 mg.
