Abstract
A process for the production of new 5,7-disubstituted xanthone-2-carboxylic acid compounds of formula: ** (See formula) ** and its non-toxic and pharmaceutically acceptable esters, amides and salts; where either the R1 groups are the same and are selected from a group of the formula (see formula) where R is amino, mono (lower) alkyl or dialkyl (lower) amino; or one of the R1 groups is selected from lower alkyl and lower alkoxy and the other R1 group is selected from the group (see formula), where R is the one previously defined; whose procedure consists of: 1) Treat with ammonia, a monoalkylamine or a dialkylamine a 5,7-di (chlorosulfonyl) -xanthone-2-carboxylic acid, a 5-alkyl- or -alkoxy-7-chlorosulfonyl-xanthone-2-carboxylic acid or an acid 5-Chlorosulfonyl-7-alkyl- or -alkoxy-xanthone-2-carboxylic to give the corresponding 5,7-sulfamoyl-, 5,7-monoalkylsulfamoyl- or 5,7-dialkylsulfamoyl-xanthone-2-carboxylic acids, 5- alkyl- or -alkoxy-7-sulfamoxy-, -monoalkylsulfamoyl- or -dialkylsulfamoyl-xanthone-2-carboxylic and 5-sulfamoyl-, -monoalkylsulfamoyl- or dialkylsulfamoyl-7-alkyl- or -alkoxy-xanthone-2-carboxylic; 2) optionally converting a product from step 1) to its pharmaceutically acceptable, non-toxic esters, amides and salts.
