Abstract
A multi-step method of producing the compound methanesulfon-m-anisidide, 4'-(9-acridinylamino)-, acetate (VII), which may be in free base form and designated NSC 249992, also known as AMSA. This compound is produced by an elegant process from a starting material, 4-butyrylamino-3-methoxy-nitrobenzene, which is later transformed to methanesulfon-m-anisidide, 4'-amino- (IV) and is coupled or joined to 9-chloro-acridine, producing the chloride salt which is later converted to the acetate.
