実験手順

A mixture of N-(6-Aminohexyl)-2-nitrobenzenesulfonamide hydrochloride (0.67 g, 2.0 mmol) and 2-naphthaldehyde(0.32 g, 2.1 mmol) in 75 mL of toluene was refluxed using a Dean Stark trap for 20 h. The reaction mixture was concentrated in vacuo. The residue was dissolved in ethanol (40 mL) and sodium borohyride (0.020 g, 6.0 mmol) was added. After the reaction was complete (6 h), the solvent was evaporated and residue taken up in 30 mL of saturated sodium chloride solution and extracted with ethyl acetate(3×40 mL), washed with saturated sodium chloride solution, dried over sodium sulfate and concetrated to afford an oil. The oil was flash chromatographed over silica gel to afford the titled compound (0.16 g, 37%) which was converted into hydrochloride salt (mp 169° C.).
