2,4,6-Tripyridino-1,3,5-triazine Trichloride, a New and Mild Esterification Agent for Preparation of Penicillin Esters
摘要:
Cyanuric chloride reacted with 3 molar equivalents of pyridine to give 2,4,6-tripyridinio-1,3,5-triazine trichloride, which was found to condense penicillins with alcohols under mild conditions to afford penicillin esters in good yields. Application to preparation of cephalosporin esters also is discussed.
