실험 절차

Potassium thiotosylate (50.0 g, 221 mmol, 1.0 eq.) and 1-bromo-3-chloropropane (38.0 g, 241 mmol, 1.09 eq.) were stirred together in acetone (1 L) at room temperature for 72 hours. The mixture was then concentrated. Next, the mixture was partitioned between dichloromethane and water. The organic solution was washed with brine (2×), dried using MgSO4, concentrated and azeotroped with toluene to produce a pale yellow oil weighing 54 g (92%).
