## Abstract A number of 8โhydroxyโ6โmethylโ1,6โnaphthyridinโ5(6__H__)โoneโ7โcarboxylic acid alkyl esters 3 and the isomeric 5โhydroxyโ7โmethylโ1,7โnaphthyridinโ8(7__H__)โoneโ6โcarboxylic acid alkyl esters 4 were synthesized from acyclic precursors obtained starting from quinolinic anhydride 5. Thus
Bwoiwd 4 homnbar 1965; in miss4 form 25 Jan-1966) J.G. Murray and C.R. Hauser (1) synthesized 3carbethoxy-4-hydroxy-l,7-naphthyridine 'I-oxide, and N. Ikekawa (2) transformed it via 4-chloro-l,7\_naphthyridine into l,7naphthyridine. We wish to report on a synthesis of 1,7-naphyridine by a different
