Abstract

NEW MATERIAL:Tetrazole derivatives of formula I (R1 is alkyl, aryl; R2 is alkyl, incoporates with R1 to form alkylene; R3 is H, alkyl, alkoxy, trifluoromethyl, halogen).
EXAMPLE: 5,5-Dimethyl-tetrazolo[4,5-c]-5H-1,3-benzoxazine.
USE: Anti-inflammatory.
PREPARATION: The reaction between an imidoyl halide of 1,3-benzoxazine of formula II (X is halogen) and an alkali metal azide such as sodium azide is effected, preferably in a solvent such as dimethylformamide at 30W100°C for 1W20hr.
