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.
