METHOD OF SYNTHESIS OF ARYLTRIAZOLINONE Russian patent published in 1998 - IPC

Abstract RU 2119918 C1

FIELD: organic chemistry and chemical technology. SUBSTANCE: invention relates to synthesis of 1-aryltriazolinone of the formula (I) where R is a lower alkyl; X is halogen, lower alkyl, nitro-, hydroxy-groups, -NHSO₂R′,-N(SO₂R′)₂,-N(R′)SO₂R′; R' is a lower alkyl; n is a whole number from 0 to 3. Method involves treatment of aryltriazolidinone of the formula (II) with hypohalogenous acid or its salt in tert.-butanol-water medium at weight ratio = (95-70): (5-30), respectively. EFFECT: improved method of synthesis, high purity degree and yield of the end product. 9 cl, 8 ex
