A mixture of 150 g of technical metribuzin 200 g water and 100 g of 70% aqueous ethylamine was heated 90° for 7.0 hours in a stirred autoclave. The contents were cooled to room temperature, the solid filtered off and dried in a circulating air oven at 60°. The crude product was recrystallized from toluene to give 74 g of analytically pure product, m.p. 177°.
