実験手順

bis-(2-Chloro-ethyl)-methyl-amine hydrochloride (3.7 g, 19.2 mmol) and sodium carbonate (9.0 g, 85 mmol) were added to a suspension of 3-bromo-quinolin-8-ylamine (3.9 g, 17.5 mmol) (for synthesis see Gershon et al., Monatsh. Chem., 1991, 122, 935) in n-butanol (70 ml). The stirred suspension was heated at reflux for 72 h. The reaction mixture was cooled to ambient temperature, diluted with dichloromethane (300 ml) and the solution washed with water (300 ml), dried (MgSO4) and concentrated in vacuo to an oil. The oil was purified by chromatography over silica gel eluting with a gradient of methanol/dichloromethane to afford the title compound (D1) as an oil (2.6 g, 8.5 mmol, 49%);
