Versuchsvorschrift

4′-[5-(Azidomethyl)-1,3,4oxadiazol-2-yl]-N-cyclopropyl-5-fluoro-6-methyl-1,1′-biphenyl-3-carboxamide (Intermediate 35) (208 mg) and palladium on carbon (10% w/w, 21 mg) in ethanol (10 ml) were hydrogenated under 1 Atm. of hydrogen for 24 hours at room temperature. The reaction was filtered through celite and the filtrate reduced to dryness under vacuum. The residue was applied to a bond-elut (silica, 10 g) and eluted with an ethyl acetate/cyclohexane gradient (50-100% ethyl acetate) and then with methanol in ethyl acetate (0-50%). The solvent was evaporated from the product fractions under vacuum to give 4′-[5-(aminomethyl)-1,3,4oxadiazol-2-yl]-N-cyclopropyl-5-fluoro-6-methyl-1,1′-biphenyl-3-carboxamide.
