Reaction Steps
6-Bromo-3,4-dihydro-2H-[1,8]naphthyridine-1-carboxylic acid amide (79 mg, 0.31 mmol), [5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyridin-3-ylmethyl]-carbamic acid tert-butyl ester (205 mg, 0.61 mmol) and 2.0 M Na2CO3 aqueous solution (0.31 mL, 0.61 mmol) are dissolved in 2.0 mL of 1,4-dioxane. Argon gas is bubbled through the solution for 5 min. Then PdCl2dppf (16 mg, 0.021 mmol) is added. The mixture is heated at 100° C. for 2 hrs and the mixture is cooled down to room temperature. Then 30 mL of EtOAc and 20 mL of water are added and the organic layer is separated. The aqueous layer is extracted with EtOAc (2×20 mL). The organic layers are combined, dried and concentrated to give the crude product. Purification by flash column chromatography affords 112 mg of [5-(8-carbamoyl-5,6,7,8-tetrahydro-[1,8]naphthyridin-3-yl)-pyridin-3-ylmethyl]-carbamic acid tert-butyl ester
