Reaction Conditions:
at 70; for 48 h;
Steps:
Trimethyloxosulfonium iodide (7)
Dimethyl sulfoxide (2 mL, 28.2 mmol) and methyl iodide (1.75 mL, 28.1 mmol) were stirred in a pressure vessel, at 70 °C for 48 hrs. The resulting precipitate was filtered, washing with CHCl3, recrystallised from H2O and dried under reduced pressure to afford clear colourless crystals (4.01 g, 18.2 mmol, 65%);
