Abstract
"Procedure for obtaining sulfonamides", of general formula, ** (See formula) ** where R is a methyl, ethyl, methoxyethyl, ethoxyethyl or propoxyethyl radical, characterized in that one of the substances 2-sulfanilamido-5-iodopyrimidine and 2-sulfanilamido-5-bromopyrimidine, or their salts, are reacted with an alcoholate of the formula Me-OR where Me means an alkali metal and R is as defined above, in the presence of a catalyst containing elemental and/or bound copper, at a higher temperature.
