실험 절차

2,6-Difluoro-N-[1,8]naphthyridin-2-ylbenzamide (35 mg, 0.12 mmol) and 10% Pd/C (15 mg) were suspended in ethanol (5 mL). Concentrated HCl (0.02 mL, 0.24 mmol) was then added and the reaction mixture was stirred under hydrogen (1 atmosphere) for three hours. Next, the reaction mixture was filtered through Celite and concentrated to give 2,6-difluoro-N-(5,6,7,8-tetrahydro[1,8]naphthyridin-2-yl)benzamide. Yield 33 mg (95%). LCMS (ESI): calc. C15H13F2N3O=289; obs. M+H=290.
