Versuchsvorschrift
2-(1-Benzyl-5-phenyl-1H-pyrazol-3-yl)-2-methylpropan-1-amine (50 mg, 0.2 mmol) was stirred under an atmosphere of hydrogen in methanol/concentrated sulfuric acid (5:1, 5 mL) with 5% palladium on carbon (350 mg). After several h, more palladium on carbon was added (350 mg). The reaction was stopped after 3 days with starting material remaining. The solution was degassed and filtered through Celite. Methanol was removed under vacuum and 1 M potassium carbonate was added until the reaction was basic. The slurry was extracted multiple times with 30% isopropanol/chloroform. The combined organic layers were dried over sodium sulfate and concentrated under reduced pressure to yield 2-methyl-2-(5-phenyl-1H-pyrazol-3-yl)propan-1-amine, which was carried through without further purification.
