Reaction Steps

In a reactor 3-buten-1-ol (33.2 g) and pyridine (230 ml) were charged and p-toluene sulfonyl chloride (96.7 g) was added thereto over 3.5 hours, while maintaining the internal temperature not higher than 5° C. under cooling in an ice bath. After stirring for 30 minutes, the reaction mixture was added to water (250 ml). Dichloromethane (250 ml) was added thereto and subjected to liquid separation. A saturated aqueous sodium carbonate solution (250 ml) and water (200 ml) were added to wash the lower layer, followed by liquid separation and washing with water (200 ml) twice, and dried over magnesium sulfate. After filtration followed by distillation to remove the solvent, 98.1 g of CH2═CH(CH2)2OTs was obtained.
