Procedure

To a microwave vial was added 5-bromo-2-([(3,4-difluorophenyl)methyl]oxy)-N-4-pyridazinylbenzamide (may be prepared as described in Example 78; 200 mg, 0.48 mmol), 4-pyridinylboronic acid (88 mg, 0.74 mmol), tetrakis(triphenylphosphine)palladium(0) (33.0 mg, 0.03 mmol), sodium carbonate (0.95 ml, 0.95 mmol) and 1,2-dimethoxyethane (3 ml). The mixture was sealed and heated to 120° C. for 1 hour under microwave conditions. The 1,2-dimethoxyethane was evaporated under reduced pressure and the residue was purified using MDAP to yield the title compound. 35 mg.
