Versuchsvorschrift

To a dry, nitrogen (N2)-purged 500 milliliter (mL) round bottom flask was added 1.15 grams (g) (4.8 mmol) sodium hydride. To this was added 150 mL dry tetrahydrofuran and 5.70 g (4.8 mmol) 2-mercaptothiazoline in 24 mL tetrahydrofuran. After approximately 15 minutes of stirring at room temperature, 5.5 mL (4.8 mmol) benzyl chloride was added and stirred for an additional 5 minutes. Tetrahydrofuran was removed by rotary evaporation and product was dissolved in hexane. After filtration, the product was recrystallized from hexane to yield 2.6 g of white crystals (26% yield). 1H NMR (CDCl3): 3.434 ppm, t, 2H; 4.259 ppm, t, 2H; 4.413 ppm, s, 2H; 7.317 ppm, m, 5H.
