0.72 g (24 mmol) of sodium hydride were added to a solution of 5.15 g (20 mmol) of 8-(4-hydroxyphenylthio)-5,6,7,8-tetrahydroquinoline in 26 ml of dimethylformamide under nitrogen. When effervescence had ceased, 3.29 g (24 mmol) of n-bromobutane were added dropwise with ice-cooling. After stirring at room temperature overnight, the mixture was poured into ice-cold water and extracted with ether to obtain a brown oil. A solution of the oil in ether was treated with ethereal hydrogen chloride to precipitate 4.89 g (70%) of 8-(4-n-butoxyphhenylthio)-5,6,7,8-tetrahydroquinoline hydrochloride as pale yellow crystals (from ethanol-ether).
