Reaction Steps

A mixture of 8-bromo-5-[5-(3,5-dichlorophenyl)-4,5-dihydro-5-(trifluoromethyl)-3-isoxazolyl]isoquinoline (i.e. the product from Step C) (20 mg, 0.04 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) (PdCl2(dppf)) (6 mg, 0.008 mmol), 2-(aminomethyl)pyridine (17 mg, 0.16 mmol) and triethylamine (0.1 mL, 0.7 mmol) in toluene (2 mL) was purged with carbon monoxide for 15 minutes. Then the reaction vial was maintained with carbon monoxide using a balloon. The reaction mixture was stirred at 70° C. under carbon monoxide atmosphere overnight. The mixture was cooled to room temperature, filtered through a short pad of Celite® diatomaceous filter and rinsed with small amount of ethyl acetate. The filtrate was concentrated and the residue was purified by column chromatography on silica gel using hexanes/ethyl acetate as eluent to provide the title product, a compound of the present invention, as a pale white solid (15 mg).
