Procedure

4-Methoxy-2-nitroaniline (2.3 g, 0.014 mol) and 2-(4-tolylsulfonyl)ethyl-4-chlorosulfonyl-2-(2-[4-tolylsulfonyl]ethoxycarbonylmethoxy)phenoxyacetate (Intermediate A16, 9.6 g, 0.014 mol) were dissolved in 40 mL of pyridine and stirred under positive nitrogen pressure. After ca. 16 hr, the mixture was diluted with 50 mL of toluene and 20 mL of dichloromethane and was concentrated at aspirator pressure. The residue was purified on a flash silica gel column (dichloromethane→5:1 dichloromethane:ethyl acetate) to yield 6.7 g (58%) of the title compound.
