반응 단계
In an ice bath, 25 g of dithioglycol was stirred and thereto, was added dropwise 1.1 equivalent of a methanol solution of sodium methoxide. Further, 44 g of ethylene chlorohydrin was added dropwise thereto. After the conclusion of the dropwise addition, the reaction mixture was allowed to stand for 10 hours at a room temperature. Then, sodium chloride deposited was removed by filtration, and the resulting filtrate was concentrated. The thus obtained white crystals were recrystallized from acetone. Melting Point 65° C., Yield 25 g.
