Reaktionsschritte

1-(3-Hydroxy-propyl)-5-trifluoromethyl-1H-pyrimidine-2,4-dione (Prep20, 100 mg, 0.42 mmol) was dissolved in dry THF (5 mL), the solution was then cooled to 0° C. and Dess-Martin periodinane (300 mg, 0.71 mmol) was added. The mixture was stirred at 0° C. for 1.5 hours. Et2O was added and the mixture washed with aqueous saturated NaHCO3 solution. The organic phase was dried (Na2SO4) and evaporated. The crude was purified by flash chromatography with ethyl acetate-petroleum ether (1-1) to give 50 mg of title compound (68% yield).
