Reaction Steps

A mixture of N-cyclopropyl-1-(3,5-dibromophenyl)-1,4-dihydro[1,8]naphthyridin-4-one-3-carboxamide from Step 2, 2-(1-hydroxy-1-methylethyl)-5-tributylstannylpyridine from Step 3 (1.4 eq), 1,1′-bis (diphenylphosphino)ferrocene]dichloropalladium(II) (0.05 eq), and cuprous iodide (0.05 eq) in N,N-dimethylformamide (15 ml/mmol) was stirred at 85° C. for 5 hours. After cooling the resulting mixture was partitioned between ethyl acetate and water. The crude product from the organic phase was chromatographed on silica gel eluting with a 1:6:3 mixture of ethanol, ethyl acetate and methylene chloride to afford the N-Cyclopropyl-1-{5-bromo-3-[6-(1-hydroxy-1-methylethyl)pyridin-3-yl]phenyl}-1,4-dihydro[1,8]naphthyridin-4-one-3-carboxamide compound as a solid.
