Procedure

A stirred suspension of (4-fluoro-phenyl)-[2-((R)-indan-1-ylamino)-quinolin-6-yl]-methanone (100 mg, 0.26 mmol), hydroxylamine hydrochloride (55 mg, 0.79 mmol) and sodium carbonate (83 mg, 0.78 mmol) in ethanol (1 ml) was heated under reflux conditions for 17 h, the reaction mixture was poured into water (20 ml) and extracted with ethyl acetate (3×75 ml). The combined organic layers were washed with brine (50 ml), dried (MgSO4) and evaporated. The crude product was further purified by flash chromatography on silica gel (heptane/ethyl acetate) and crystallization (ethyl acetate/heptane) to yield the title compound as white solid (61 mg, 59%).
