PROCEDURE

实验过程

1.5 g of 4-(4-chloro-3-sulfamoylphenyl)-3-methyl-2-methylimino-1,3-thiazolidine-4-ol were stirred in 10 ml of ethanol with 0.7 of maleic acid for 1 hour at room temperature, the salt desired was precipitated with 50 ml of diisopropyl ether and crystallized under fresh diisopropyl ether/ethyl acetate to yield colorless crystals which melted at 167° C (decomposition).
