Reaction Steps

To a stirred suspension of 3 g (0.01 mol) of sulfone (described in Example 3) in 15 mL of dry dimethylformamide cooled in an ice bath, is added 0.5 g sodium hydroxide powder. To this mixture is slowly added 0.75 mL methyl iodide. The reaction mixture is warmed to room temperature and stirred for 2 hours. 100 mL ice-water is slowly added with stirring. After filtration the white solid is recrystallized from toluene. Melting point: 146°-147° C. Structure confirmed by NMR. I.R. N→O 1250 cm-1, SO2 1350, 1140 cm-1.
