    摘要: A compound of the formula:
    wherein R 1 is amino or a protected amino group,

    X is N or CH, and
    R 5 is ethyl, cyclo (lower) alkyl, cyclo (lower) alkenyl, lower alkyl having a protected carboxy group, lower alkynyl or lower alkylthio(lower)alkyl,
    provided that X is N when R 5 is lower alkynyl and
    R' is amino when R 5 is ethyl, or a salt therof, and processes fortheir preparation. The compounds are useful as starting material for the preparation of pharmaceutically active cephem compounds.
