Abstract

PURPOSE: To obtain the titled compound having germicidal and antitumor activities with low toxicity readily, by dissolving a specific compound in methyl cellosolve, and reacting the cmpound with a salicylic acid solution in methyl cellosolve under given conditions.
CONSTITUTION: One molar amount of a compound expressed by the formula (R is H or dichloroacetyl chloride group; R1 and R2 are diazosulfamide group) is dissolved in ethylene glycol monomethyl ether (methyl cellosolve), and an equal amount of a solution of salicylic acid or a derivative thereof in methyl cellosolve is added to the solution and reacted under neutral or alkaline conditions to afford a salicylic acid double salt.
