    摘要: The present invention relates to a simple process for producing 2-aminothiazoleacetic acid derivatives useful as intermediates for producing cephalosporin-type antibiotics. The process for producing chloroacetylaminothiazoleacetic acid derivatives represented by the following formula (II)
       wherein R1 is a protection group for the hydroxyl group,
    comprises reacting aminothiazoleacetic acid derivatives represented by the following formula (I)
       wherein R1 is a protection group for the hydroxyl group,
    with a chloroacetylating agent.
