摘要

(CH3)* NCH (OCH& here such a synthesis of lH-indole-6-NJV-dimethyl-sulfonamide (3) and of the indicator dye 11.% It was anticipated that the method of Batcho and Leimgrubel. 9 might be well-suited for the general preparation of indole-&sulfonamides. We found, however, that, as described in the following text, the scope of the procedure was effectively limited to symmetrical tertiary sulfonamides. The synthesis of the sulfonamide series ...
