N¹-3, 4-Dimethylbenzoylsulfanilamide, 3, 4-dimethylsulfanilamidoisoxazole, and 6-sulfanilamido-2, 4-dimethylpyrimidine were successfully titrated in methanol-benzene mixture or pyridine, with 0.1N sodium methoxide, using thymol blue as the indicator. Analysis of variance indicated that the standard deviation of experimental error was 0.3%. The end point was more clear in pyridine solution.
