실험 절차

To a solution of ethyl 4-[2-azido-4-chloro-7-(1-ethylpropyl)-1H-benzimidazol-1-yl]butanoate (190 mg, 0.500 mmol) in tetrahydrofuran (3.0 mL) was added lithium aluminum hydride (57 mg, 1.5 mmol) portionwise at 0° C. After stirring for 1 hr, sodium sulfate decahydrate (300 mg) was added to the mixture, which was stirred for 1 hr. Insoluble materials were filtered off and the filtrate was concentrated in vacuo to give the title compound (135 mg, 0.435 mmol, 87%) as a colorless solid.
