Synthesis of 1-(5-methylisoxazole-3-yl)-5-aryl-tetrazoles and its pyrolysis
Vasu, Kamala K.,Reddy, K. Kondal
, p. 2847 - 2857 (1999)
3-Aroylamino-5-methylisoxazoles (2) were obtained by the reaction of 3- amino-5-methylisoxazole (1) with different aroyl chlorides. These amides on reaction with phosphorous pentachloride followed by sodium azide yielded 1- (5-methylisoxazole-3-yl)-5-aryl
