Reaction Steps

6-[5-(4-Fluoro-phenoxymethyl)-pyridin-3-yl]-1,2,3,4-tetrahydro-[1,8]naphthyridine (32 mg, 0.096 mmol) and benzoyl isocyanate (24 mg, 0.14 mmol) are mixed in 1.0 mL of DCM and the mixture is heated at 50° C. for 16 hrs. Then the solvent is removed and the residue is dissolved in 1.0 mL of EtOH. K2CO3 (23 mg, 0.16 mmol) is added and the mixture is heated at 80° C. for 45 min. Then 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 EtOAc (2×30 mL). The organic layers are combined and concentrated to give the crude product. Purification by flash column chromatography affords 26 mg of the titled product.
