Abstract

2-(7.alpha.-Alkoxy-7.beta.-benzylideneamino-3-cephem-4-carbonyl)-s-triazolo ¢4,3-a) pyrid-3-one derivatives are prepared by reacting the corresponding 2-(7-benzylideneamino-3-cephem-4-carbonyl)-s-triazolo ¢4,3-a) pyrid-3-ones with a benzoquinone having an electron-attracting substituent, and reacting the product with a lower alkanol. The compounds produced are useful as intermediates in the synthesis of cephalosporin antibiotics.
