# Oxidation of Amines to Nitroso Compounds

## Oxidation of Amines to N-Nitrosamines: Experimental Procedure

The required nitrosyl cation is generated at 10$°C$ by the addition of sodium nitrite to concentrated sulfuric acid. The mixture is warmed to room temperature and the amine is added. After first heating the mixture to 70$°C$ , it is cooled down to room temperature and after three hours excess nitrite is destroyed by the addition of urea.
