Procedure

A mixture of N-cyclopropyl-1-(3-bromophenyl)-1,4-dihydro[1,8]naphthyridin-4-one-3-carboxamide, boronate from Step 1 (1.2 eq), palladium acetate (0.1 eq), triphenylphosphine (0.35 eq) and 2M aqueous sodium carbonate (3.5 eq) in n-propanol (10 ml/mmol) was stirred at 85° C. for 1 hour. After cooling, the mixture was quenched with saturated aqueous ammonium chloride solution and partitioned between ethyl acetate and water, and the product from the organic phase was chromatographed on silica gel eluting with a 1:5:4 mixture of ethanol, ethyl acetate and methylene chloride to afford the N-Cyclopropyl-1-[3-(4-sulfamoylphenyl)phenyl]-1,4-dihydro[1,8]naphthyridin-4-one-3-carboxamide compound as a solid.
