—— | 5-methyl-1-phenyl-1H-tetrazole | 14213-16-2 | C8H8N4 | 160.178 |
A number of N-arylisoxazol-5(2H)-ones (aryl = phenyl, isoquinolin-1-yl, quinolin-2-yl, 2-phenylquinazolin-4-yl and benzothiazol-2-yl) have been reacted with lithium azide to give 2-(1-aryltetrazol-5-yl)acetic esters, which have been C- methylated and hydrolysed. The resulting 2-(1-aryltetrazol-5-yl) propanoic acids had low antiinflammatory activity, as judged by inhibition of synthesis of prostaglandin PGE2 or tumour necrosis factor α.
