Procedure
The above phenyl methylsulfonylmethanesulfonate (25 g, 0.1 mole) was dissolved in a solution of 75 mL of water and 8 g (0.1 mole) of 50% sodium hydroxide. The solution was cooled to 0-5° C. and treated with 11.4 g of methanesulfonyl chloride which was added dropwise over 45 min. The resulting slurry was filtered (starting material precipitates during the addition) and the solid (14.3 g after drying) was washed with 75 mL of water. The filtrate was treated with conc HCl until no more solid precipitated. The phenyl bis(methylsulfonyl)methanesulfonate product was filtered and washed with ice-water. After drying in a 60° C. vacuum oven the product (12.9 g, mp 154-156° C.) was recrystallized from ethyl acetate with a hot clarification to give 11.3 g, (34.4% conversion, 80% yield) of phenyl bis(methylsulfonyl)methanesulfonate as a white solid, mp 159-160° C. H1NMR: δ 7.36-7.44 (m, 5H); δ 2.65 (s, 6H). No major impurities were detected by HPLC-MS.
