実験手順

A mixture of 6-(1-azido-2,2,2-trifluoroethyl)-9-chloro-1-(2,4,6-trichlorophenyl)-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazole (286 mg, 0.560 mmol), triphenylphosphine (220 mg, 0.839 mmol) and water (0.560 mL) in tetrahydrofuran (5.6 mL) was stirred at 60° C. for 1 day. After the mixture was diluted with ethyl acetate, the resultant mixture was extracted with 1N hydrochloric acid. The extract was washed with diethyl ether and neutralized with aqueous saturated sodium hydrogen carbonate. The resultant mixture was extracted with ethyl acetate. The extract was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to give the title compound as a colorless solid (257 mg, 0.532 mmol, 95%).
