Versuchsvorschrift

Dess-Martin reagent (207 mg, 0.487 mmol) was added to a stirred solution of 1-[9-chloro-1-(2-methoxy-4,6-dimethylpyrimidin-5-yl)-1,2,3,4-tetrahydropyrimido [1,2- a]benzimidazol-6-yl]propan-1-ol (178 mg, 0.443 mmol) in dimethyl sulfoxide (1.0 mL) and acetonitrile (3.0 mL) at 0 ° C., and the mixture was stirred at 0 ° C. for 30 min. The mixture was diluted with saturated aqueous sodium hydrogen carbonate, and extracted with ethyl acetate. The combined organic layer was washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated in vacuo to give the title compound as a yellow solid (172 mg, 0.430 mmol, 97%).
