After completion of the reaction, the reaction mixture was cooled to room temperature and acidified with 6N hydrochloric acid. The aqueous layer was washed with ethyl acetate and made basic with an aqueous sodium hydroxide solution, 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 0.52 g of 2-methyl-1-phenylthio-2-propylamine was obtained (yield: 57%).
