4,6-Dimethylpyrimidine Use and Manufacturing

Methods of Manufacturing

General procedure: Irradiation procedure. The dimethylpyrazine or dimethylpyrimidine was placed in a Pyrex tube, attached to the vacuum line, and subjected to three freeze-thaw cycles. The remaining material was then allowed to vaporize into a quartz reaction flask (3 L) that had been evacuated overnight. The resulting pressure in the reaction flask ranged from 1.0 to 1.5 Torr. The flask was irradiated for 5 min. in a Rayonet reaction equipped with either 2, 4, 6, 8, or 10 low-pressure 2537 Å Hg lamps.General procedure: Irradiation procedure.
