Acetic Acid → HCID 67095880, compound

Participants

Reaction Steps

To a stirred solution of acetic acid (127 mg, 2.12 mmol) in acetonitrile (8.5 ml) was added at room temperature 1-hydroxy-benzotriazole (403 mg, 2.98 mmol) and N-(3-dimethylaminopropyl)-N′-ethyl-carbodiimid-hydrochloride (465 mg, 2.43 mmol). The mixture was allowed to stir for 3 h at room temperature and N-hydroxy-2-((R)-indan-1-ylamino)-quinoline-5-carboxamidine (450 mg, 1.41 mmol) was added together with acetonitrile (7.5 ml). The mixture was allowed to stir for 2 h at room temperature, evaporated to dryness and diluted with acetic acid (14 ml). The reaction mixture was allowed to stir for 2 h at 100° C., evaporated, poured into saturated NaHCO3 solution (50 ml) and extracted with ethyl acetate (3×80 ml). The combined organic layers were washed with brine (2×50 ml), dried (MgSO4) and evaporated. The crude product was purified by flash chromatography (ethyl acetate/heptane) on silica gel and crystallization (ethyl acetate/heptane) to yield the title compound as light yellow solid (130 mg, 18%).
