Procedure
Phosphorus oxychloride (0.75 ml) was added to a stirred solution of 5-cyano-4-(3-methoxyphenyl)-2-methylthio-6-hydroxy-pyrimidine (example 1a, 305 mg) in dry 1,4-dioxane (1 ml). A drop of N,N-dimethylaniline was added. After 3 h at 80° C., the mixture was cooled to 0° C. in an ice bath and crushed ice was slowly added. After cessation of the exothermic reaction, H2O (3 ml) was added. The solids were collected by filtration and dried in vacuo.
