실험 절차

Acetic acid (0.14 mL, 2.38 mmol) was added dropwise into a mixture of 4-{[(2S)-3-amino-2-hydroxypropyl]oxy}-1,3-dihydro-2H-benzimidazol-2-one (265 mg, 1.19 mmol), 1-[[4-(4-oxo-1-piperidinyl)phenyl]sulfonyl]-2,4-imidazolidinedione (400 mg, 1.19 mmol) and N,N-dimethylformamide (5 mL). The mixture was stirred for 20 minutes and then, sodium triacetoxyborohydride (303 mg, 1.43 mmol) was added, and the new mixture was stirred at room temperature for 24 hours. The volatiles were removed in vacuo and the residue was purified by flash chromatography (dichloromethane/methyl alcohol 3/1) to produce a brown solid (256 mg, 40% yield): mp 230° C.
