Procedure
A mixture of N-Isopropyl-1-(3-bromophenyl)-1,4-dihydro[1,8]naphthyridin-4-one-3-carboxamide from Step 4, 3-acetylphenylboronic acid (1.2 eq.), trans-dibromobis(triphenylphosphine)palladium (II) (0.05 eq.), toluene (6 mL/mmol), ethanol (2 mL/mmol) and 2M aqueous sodium carbonate (8 eq.) was refluxed for 1 hour under a nitrogen atmosphere. The mixture was diluted with ethyl acetate and the organic phase was washed with water and brine, dried and evaporated. The crude product was chromatographed on silica gel eluting with a gradient of 20-40% ether in methylene chloride to afford the N-Isopropyl-1-[3-(3-acetylphenyl)phenyl]-1,4-dihydro[1,8]naphthyridin-4-one-3-carboxamide product as a solid.
