Reaction Steps
2-Aminobenzenesulfonamide was used as starting material for the following transformation sequence: Method E (using 4-chlorobutanoyl chloride. The reaction mixture was NOT subjected to NaOH catalyzed ring closure, but dissolved in H2SO4 and heated at 100° C. for 72 h and precipitated on ice). M.p. 149-154° C.
