Versuchsvorschrift

Platinum dioxide (1.9 mg, 0.0082 mmol) was added to a solution of tert-butyl [3-[({7-[(7-oxo-7,8-dihydro-1,8-naphthyridin-4-yl)oxy]-1,2,3,4-tetrahydronaphthalen-2-yl}-carbonyl)amino]-5-(trifluoromethyl)benzyl]carbamate (20 mg, 0.033 mmol) in AcOH (0.5 mL). The solution was allowed to stir under an atmosphere of hydrogen at rt. After 28 hr, an additional amount of platinum dioxide was added (1.9 mg, 0.0082 mmol) and the reaction continued to stir under an atmosphere of hydrogen for a total of 46 h. The reaction mixture was then filtered through Celite and the residue was purified by column chromatography to give tert-butyl [3-[({7-[(7-oxo-5,6,7,8-tetrahydro-1,8-naphthyridin-4-yl)oxy]-1,2,3,4tetrahydronaphthalen-2-yl}carbonyl)amino]-5-(trifluoromethyl)benzyl]carbamate (9.0 mg, 45%) as a white solid. LCMS: (FA) ES+ 611.4.
