Abstract

Improvements made to the subject of main patent No. 388,787 applied for on March 2, 1971 for "A process for preparing new quinoxaline-1,4-dioxides, 2-heterocyclic substituted" of the formulas: where X is a substituent at the 6 or 7 position and is hydrogen, chlorine, bromine, fluorine, methyl, methoxy or trifluoromethyl; A is alkylene of 2 to 5 carbon atoms; and Z is acyloxy of the formula -O2CR where R is an alkyl group containing from 4 to 10 carbon atoms; alkoxy containing 1 to 4 carbon atoms, alkylamino containing 1 to 4 carbon atoms; carboxyalkyl containing from 2 to 8 carbon atoms; or substituted alkyl wherein said alkyl group contains 1 to 3 carbon atoms and the substituent is fluorine, bromine or dialkylamino in which the alkyl portion contains 1 to 3 carbon atoms; acid addition salts thereof where Z is acyloxy of the formula -O2CR where R is dialkylaminoalkyl; pharmaceutically acceptable basic salts thereof where Z is acyloxy of the formula -O2CR where R is carboxyalkyl; and lower alkyl quaternary salts thereof, wherein said lower alkyl contains 1 to 3 carbon atoms, and the salt is a pharmaceutically acceptable anion and R is dialkylaminoalkyl, characterized by (a) reacting, in the presence of a base, an appropriate benzofuroxane of the formula: **(See formula)** where X is as previously defined, with a reagent selected from **(See formula)** where A and Z are as previously defined; or **(See formula)** where A and Z are as previously defined; (b) reacting a 3-C1-C3-alkyl-quinoxalincarboxylic acid ester of the formula: **(See formula)** with an alkanol of the formula: HO-A-Z where A, X and Z are as previously defined and M is lower alkyl or phenyl.
