Reaction Steps

A solution of 3-(1-methyl-4-nitro-1H-pyrazol-3-yl)-1,3-oxazolidin-2-one (58 mg), pentafluorophenyl 2-(2-((tert-butoxycarbonyl) (2,2,2-trifluoroethyl)amino)pyridin-4-yl)-1,3-oxazole-4-carboxylate (197 mg), 10% palladium-carbon (29 mg) and triethylamine (76 μL) in methanol (1.4 mL) was stirred overnight at room temperature under hydrogen atmosphere. The reaction mixture was filtered through Celite, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (28 mg).
