Reaction Steps
To a solution of 2.0 g of 2-anilino-4,6-dimethylpyrimidine in 15 ml of acetic acid was added dropwise a solution of 1.4 g of sodium nitrite in 10 ml of water. After 30 minute's stirring, 50 ml of water was added to the mixture. The resulting crystals were collected by filtration and dried. Recrystallization from ethanol afforded 1.7 g (yield: 74%) of 4,6-dimethyl-2-(N-nitrosoanilino)pyrimidine having a melting point of 117°-121° C.
