Reaction Conditions

Reaction Steps

At room temperature, 45.95 g of N-(4,6-dihydroxy-2-methylsulfanylpyrimidin-5-yl)-4-methoxy-3,5-dimethylbenzamide were suspended with stirring in 125 ml of phosphorus oxychloride, and the mixture was heated at 70° C. for 36 hours. After cooling, the reaction mixture was sucked through a glass frit, giving a yellow solid which was introduced with stirring into a saturated aqueous sodium bisulfate solution and stirred for 10 min. The solid was then filtered off with suction, washed until neutral and dried. This gave 10.47 g (22%) of the title compound, which was reacted further without any further purification.
