The acylation of benzene, toluene, and chlorobenzene with cinchomeronic acid anhydride in the presence of AlCl3, has given in each case both possible isomers of the corresponding aroylpyridine carboxylic acid.It was found that the yields of reaction products and their isomeric compositions depend on the conditions of performing the reaction.The intramolecular cyclization on the isomeric keto acids in the presence of 2percent oleum has given 2-azaanthraquinone and chlorine derivatives of it.
