invention specifically 3 nitrophenol can first react with a brominated aromatic compound via a substitution reaction to form an alkoxy containing compound the alkoxy containing compound can then be reduced e g by hydrogen or tin chloride to convert the nitro group to an amino group the compound thus formed can then be treated with thiocarbonyl diimidazole tcdi and a base e g ammonia to form a compound of the invention e g compounds 1 14 21 31 82 140 and 143 183 certain other compounds of the invention can be prepared from benzene 1 3 diamine for example as shown in scheme ii below one of the amino groups on benzene 1 3 diamine can be first protected with a tert butyloxycarbonyl boc protecting group the other amino group on benzene 1 3 diamine can then react with a brominated aromatic compound the compound thus formed can subsequently be deprotected and then treated with thiocarbonyl diimidazole and a base to form compounds of the invention such as compounds 15 20 certain other compounds of the invention can be prepared from a monoamine aromatic compound for example as shown in scheme iii below a monoamino aromatic compound can react with thiocarbonyl diimidazole followed by ammonia or a primary amine to form a compound.
