実験手順
t-Butyl 2-bromo-2-(3,5-dichlorophenoxy)acetate (1.0 g) was dissolved in 1,4-dioxane (3 ml), and sodium thiomethoxide (0.218 g) was added to the mixture. The resulting pale yellow suspension was stirred at ambient temperature for 5 hours and then stored for 18 hours. The solvent was evaporated, water was added and the aqueous layer was extracted twice with ethyl acetate (100 ml). The organic layers were combined, washed with brine, dried over magnesium sulphate, filtered and evaporated to give t-butyl 2-methylthio-2-(3,5-dichlorophenoxy)acetate as a pale yellow solid (0.80 g) which was used in the next step without further purification.
