Reaction Steps

1-[5-(5,6,7,8-Tetrahydro-[1,8]naphthyridin-3-yl)-pyridin-3-yl]-ethanone (50 mg, 0.20 mmol) and benzoyl isocyanate (48 mg, 0.30 mmol) are dissolved in 2.0 mL of DCM. The mixture is heated at 50° C. for 16 hrs. Then the solvent is removed in vacuum and the residue is dissolved in 2.0 mL of EtOH. K2CO3 (46 mg, 0.34 mmol) is added and the mixture is heated at 80° C. for 45 min. The solvent is removed and the residue is partitioned between water (35 mL) and EtOAc (75 mL). The aqueous layer is separated and extracted with DCM (2×30 mL). The organic layers are combined and concentrated to give the crude product. EtOAc (2 mL) is added to the crude and the white solid formed is filtered, rinsed with more EtOAc (2×3 mL) and dried to give 30 mg of the titled product.
