実験手順
2-Dimethylaminoethanethiol hydrochloride (3.4 g.) was added to a suspension of sodium hydride (2.32 g. of a 50% w/w dispersion in mineral oil) in dimethylformamide (25 ml.) at 0° to 5°. When all the hydrogen had evolved, 2-chloro-3-isopropylquinoline (4.0 g.) was added and the mixture heated at 80° for 5 hr. The reaction mixture was then poured into ice water (500 ml.) and extracted with ethyl acetate (3×120 ml.). The ethyl acetate extract was washed successively with water (100 ml.) and saturated brine (100 ml.) and then dried (MgSO4). The ethyl acetate solution was evaporated and the residual oil was chromatographed on basic alumina (70 g.; Brockmann Grade III), eluted with increasing concentrations of chloroform in petroleum ether. The eluate obtained with 20% v/v chloroform in petroleum ether was evaporated, the residual oil was dissolved in diethyl ether, and ethereal hydrogen chloride was added until precipitation was complete. The solid residue was collected by filtration and crystallised from ethanol-diethyl ether to give 2-(2-dimethylaminoethylthio)-3-isopropylquinoline hydrochloride, m.p. 164°-7°.
