Procedure

A mixture of 110.6 g of the product of Example 32, 49.8 g of anhydrous potassium carbonate, 55.8 g of methyliodide and 500 ml of acetone was stirred at ambient temperature for 20 hours. The solvent was evaporated and the residue partitioned between methylene chloride and water. Concentration of the organic extract afforded 88.9 g of N-methyl-N-(phenylmethoxy)-2-nitrobenzenesulfonamide as a yellow oil. [NMR:δ 2.8(s, 3H, NCH3)].
