Versuchsvorschrift
A suspension of 5-(4-methyl-3-nitrophenyl)-pyrimidine (258 mg) in tetrahydrofuran (5ml) and methanol (5 ml) was hydrogenated over palladium on carbon (10% w/w, 50% wet, 130 mg) under hydrogen atmosphere for 4 hours. The catalyst was filtered off and the filtrate was evaporated to give 5-(3-amino4-methylphenyl)pyrimidine(410 mg, 96.5%).
