실험 절차

75 g (427 mmol) of 4-amino-6-chloro-2-(methylthio)pyrimidine are dissolved in 3000 ml of dioxane and 750 ml of water. 101.05 g (597.81 mmol) of bromoacetaldehyde dimethyl acetal are added, and the mixture is heated under reflux for 24 h. After the reaction is complete, the dioxane is removed in vacuo and the aqueous suspension is suspended in THF, filtered with suction and washed with some THF. Drying of the solid at 40° C. under high vacuum results in 56.5 g (66% of theory) of the product.
