実験手順
The starting material, 2-bromobenzene-1-sulfonamide, is commercially available. Reaction of 2-bromobenzene-1-sulfonamide in a solvent such as DMF, with 1,1-dimethoxy-N,N-dimethylmethanamine, followed by the addition of sodium hydrogen sulfate in water, yields 2-bromo-N-[1-dimethylaminometh-(E)-ylidene]benzenesulfonamide. This compound is reacted with 4-methylphenylboronic acid to yield 4′-methylbiphenyl-2-sulfonic acid 1-dimethylaminometh-(E)-ylideneamide, then the —(CH2)r-L1 moiety is added, for example, by a halogenation reaction, to form compound (1).
