To the suspension were added 0.85 g (5 mmol) of 2-amino-2-methylpropyl hydrogensulfate and 0.73 g (5 mmol) of 1-octanethiol, and the resulting mixture was gently refluxed for 8 hours. After completion of the reaction, the reaction mixture was cooled to room temperature and the desired compound was extracted three times with ethyl acetate. The combined organic layer was washed with saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate, and then distilled under reduced pressure to remove the solvent, whereby 1.08 g of 2-methyl-1-n-octylthio-2-propylamine was obtained. The purity was measured in terms of area percentage by gas chromatography and found to be 91%.
