    • Synthesis of 1,1--thiobis-(2-naphthoxy(2-methyl acetate)) (2): To a mixture of 1 (6.04 g, 19 mmol), potassium carbonate (5.24 g, 38 mmol), and potassium iodide (catalytic) in acetonitrile (100 mL) at room temperature, methylchloroacetate (3.35 mL, 38 mmol) was added. Then the reaction mixture was refluxed for 24 h. After completion of the reaction (TLC), the mixture was cooled to room temperature, water was added and extracted with chloroform (3 × 50 mL). The mixture was washed with sodium hydroxide solution (10%), dried, and evaporated to afford a precipitate that recrystallized from ethanol, to give pure 2 in 91% yield.
