Abstract

NEW MATERIAL:A compound of formula I: (R1 is amino or formylamino group; R2 is n-propyl or hexyl group; R3 is carboxy or hexanoyloxymethoxycarbonyl group), and its salt.
EXAMPLE: 2-Methyl-7-[2-n-hexyloxy-imino-2-(2-formylamino thiazol-4-yl) acetamido]- 3-cephem-4-carboxylic acid (syn-isomer).
USE: Antibacterials.
PROCESS: The compound of formula I is obtained as follows: (a) A compound of formula II is reacted with a compound of formula III or its reactive derivative. (b) A compound of formula I wherein R1 is formylamino group is deformylated to give the compound of formula I: (R1 is amino group). (C) A compound of formula I: (R3 is carboxyl group) is esterified to give the compound of formula I: (R3 is hexanoyloxymethoxycarbonyl group).
