Abstract
PURPOSE: To obtain in high yields the titled compound useful as a coupling component of dye, by reacting a compound, e.g., glycine, with a cyanoacetate and acetoacetate as raw materials in arbitrary order or simultaneously, followed by further hydrolysis, if necessary.
CONSTITUTION: A compound (e.g., glycine, taurine, etc.) shown by the formula Z-NH2 (Z is 1W5C alkyl having one or two SO3H or COOH) is reacted with a compound shown by the formula NCCH2COOR1 (R1 is alkyl) and a compound shown by formula CH3COCH2COOR2 (R2 is alkyl) in an arbitrary order or simultaneously in an aqueous solvent in the presence of a basic compound to give a 6- hydroxy-pyrido-2-one compound shown by the formula I. This compound shown by the formula I is further hydrolyzed with conc sulfuric acid to give a 6-hydroxy- pyrido-2-one compound shown by the formula II.
