실험 절차

A mixture of 1-[9-chloro-1-(3,5-dichloropyridin-2-yl)-1,2,3,4-tetrahydropyrimido[1,2-a]benzimidazol-6-yl]propan-1-ol (112 mg, 0.272 mmol), cyclopropanecarboxylic acid (35.1 mg, 0.408 mmol), 4-dimethylaminopyridine (49.8 mg, 0.408 mmol), triethylamine (76 μL) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (104 mg, 0.544 mmol) in tetrahydrofuran (2.0 mL) was stirred at room temperature for 13 hr. The mixture was diluted with water 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 purified by flash column chromatography on silica gel eluting with a 10-50% ethyl acetate/n-hexane gradient mixture. The filtrate was concentrated in vacuo to give the solid, which was recrystallized from ethyl acetate/diisopropyl ether to give the title compound as a colorless crystal (93.5 mg, 0.195 mmol, 72%)
