    Abstract: Disclosed is a process for preparing substituted pyridone compounds which comprises (a) admixing in the absence of a solvent (1) an amine of the formula R1nullNH2 wherein R1 is an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group, and (2) a first ester of the formula 1 wherein R2 is an electron withdrawing group and R3 is an alkyl group; (b) heating the mixture containing the amine and the first ester to form an intermediate compound of the formula 2 (c) admixing the intermediate compound with (1) a base and (2) a second ester of the formula 3 wherein R4 is an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group and R5 is an alkyl group, said second ester being present in a molar excess relative to the intermediate compound, said base being present in a molar excess relative to the intermediate compound, and (d) heating the mixture containing the intermediate compound, the second ester, and the base to form a pyridone compound of the formula 4 or a salt thereof. Also disclosed is a process for preparing diazopyridone colorants which comprises preparing a pyridone compound by the above process and reacting the pyridone compound with a diazonium salt to form a diazopyridone compound.
