Reaction Steps

Under a protective-gas atmosphere, a mixture of 9.2 g (0.055 mol) of 4,6-dimethyl-1-(2-hydroxyethyl)pyrimidin-2(1H)-one and 13.1 g (0.068 mol) of methyl p-toluenesulfonate in 700 ml of acetonitrile was heated under reflux for 12 hours. After cooling, about ⅔ of the solvent was removed on a rotary evaporator, the remaining residue was mixed with the same amount of diethyl ether and cooled to 0° C. At low temperature, firstly an oil separated off, which crystallized out after some time. The crystalline product was filtered off.
