Abstract

NEW MATERIAL:The title compound shown by the formula I (R is lower alkyl; R1 is H or lower alkoxy; R2 is lower alkyl) and its salt.
EXAMPLE: 7β-( 4-Methylimino-1, 3-dithethane-2-yl )carboxamide-7α-methoxy-3-(1- methyltetrazol-5-yl) thiomethyl-Δ3-cephem-4-carboxylic acid.
USE: An antibacterial substance.
PROCESS: A compound shown by the formula II (X is halogen) is reacted with a compound shown by the formula III (Me is alkali metal) to give the desired compound shown by the formula I. A compound shown by the formula IV (R3 is H or carboxyl-protecting group) is reacted with a compound shown by the formula V or its reactive derivative to give the desired compound shown by the formula I. After the reaction, when R3 is the protecting group, it is removed to give the desired compound.
