Procedure

A freshly prepared solution of diazomethane in anhydrous ether was added in excess to a solution of N-[2-(2-tert-butylphenylcarboxy)-1,1-dimethylethyl]trifluoromethanesulfonamide (13.1 g) in ether. The resulting yellow solution was allowed to stand at RT overnight, then was washed with 10% HCl followed by 2.5N aq NaOH. The organic solution was dried (MgSO4), and concentrated to afford 13.0 g of pure N-methyl-N-[2-(2-tert-butylphenylcarboxy)-1,1-dimethylethyl)trifluoromethanesulfonamide as a white solid, a 96% yield. m.p. 42°-44° C.
