Procedure
A solution of chloroacetyl chloride (4.4 ml) in dichloromethane (40 ml) was added dropwise to a cooled and stirred solution of 5-t-butyl-2-methoxy-3-aminophenyl N-t-butyl-sulfonamide (15.6 g) and diisopropylethylamine (9.5 ml) in dichloromethane (100 ml). The solution was left standing at ambient temperature for 2 hours and then washed with a 2% solution of citric acid. The organic phase was dried and evaporated. Recrytallization from aqueous ethanol gave the title compound (16.4 g).
