実験手順

Sulfur trioxide-pyridine complex (23.4 g, 147 mmol) was added to a stirred solution of {9-chloro-1-[4-chloro-2-(trifluoromethyl)phenyl]-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazol-6-yl}methanol (8.72 g, 20.9 mmol), triethylamine (23.3 mL), and dimethyl sulfoxide (140 mL) in dichloromethane (30 mL) at room temperature, and the mixture was stirred at room temperature for 3 hr. 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. The residue was washed with diisopropyl ether to give the title compound as a colorless powder (6.90 g, 16.7 mmol, 80%).
