Versuchsvorschrift

A suspension of 5-(2-methyl-5-nitrophenyl)pyrimidine (0.431 g) in tetrahydrofuran (4 ml) and methanol (4 ml) was hydrogenated over palladium on carbon (10% w/w, 50% wet, 129 mg) under hydrogen atmosphere for 2 hours. The catalyst was filtered off, and the filtrate was evaporated under reduced pressure to give 5-(5-amino-2-methylphenyl)pyrimidine (370 mg, 99.7%).

Aufarbeitung

  1. filtrationThe catalyst was filtered off
  2. customthe filtrate was evaporated under reduced pressure
