To a mixture of 3-methylthio-1-propanol tosylate (14.14 g, 54.3 mmol), and 3-mercapto-1-propanol (5.0 g, 54.3 mmol) in dry THF (300 mL) was added potassium tert-butoxide (8.51 g, 80.0 mmol) in one portion under a blanket of nitrogen, and the resulting mixture was stirred at room temperature for 24 hours. Water (10 mL) was added drop-wise to the reaction mixture to quench excess potassium tert-butoxide, and solvent was evaporated under reduced pressure. The resulting solid was washed with ether (3×100 mL), and filtered. The ether layer was washed with water (3×100 mL) and dried (Na2SO4). Solvent evaporation produced 8.7 g of a light yellow oil. This product was used for acryloylation without further purification.
