    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a thiazole carboxylic ester.
    SOLUTION: A method for producing a compound represented by formula VI is characterized by reacting a thioamide represented by formula IV and a bromopyruvic ester represented by formula V:[wherein, R
    1 indicates a branched or straight chained 1-4C alkyl] in a alcohol, R
    2 OH (wherein, R
    2 indicates a branched or straight chained 1-8C alkyl, HO-CH
    2 -CH
    2 , HO-CH
    2 -CH
    2 -CH
    2 - or 1-4C alkyl-O-CH
    2 -CH
    2 -) at -5°C to 40°C.
