Procedure
To a solution of [9-chloro-1-(2-chloro-4-methoxyphenyl)-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazol-6-yl]methanol (143.5 mg, 0.379 mmol) in dimethylsulfoxide (2.0 mL) was added Dess-Martin reagent (177.0 mg, 0.417 mmol). The reaction mixture was stirred at room temperature for 2 hrs. The mixture was quenched with aqueous saturated sodium hydrogen carbonate and aqueous saturated sodium thiosulfate. The generated precipitate was collected by filtration and washed with water to give the title compound as a colorless solid (129.6 mg, 0.344 mmol, 91%).
