Reaction Steps

In 50 ml of hexamethyldisilazane, 6.16 g of 5-trifluoromethyluracil was suspended and then 0.22 ml of trimethylchlorosilane was added to the suspension, followed by heating the resulting mixture to reflux for 5 hours. After the reaction, the excess hexamethyldisilazane was removed by evaporation and the resultant was distilled in vacuum. All of the fractions of distillate obtained at about 60° C. under 1 mmHg were collected. Yield: 10.3 g
