Versuchsvorschrift

A mixture of 1.5 g of thiourea and 4 g of 2,4-bis(ethylamino)-6-chloro-1,3,5-triazine in a mixture of 20 ml of dioxane and 20 ml of water is refluxed with stirring for 2 hours in 100 ml flask. After cooling, the mixture is mixed with 1.6 g of 50% sodium hydroxide and stirred for 10 minutes. The resulting mixture is neutralized with hydrochloric acid and extracted with ethyl acetate. The extract is concentrated under reduced pressure to give 4 g of 2,4-bis(ethylamino-6-mercapto-1,3,5-triazine. The product can be used for preparation of the objective compound without isolation.
