| titleOfInvention | A new process for preparing 4-[4-methyl-5-(c1-10alkylthio/c5-10aryl-c1-6alkylthio)-4h-1,2,4-triazol-3-yl]pyridines |
| abstract | The invention relates to a method of manufacturing a compound according to formula (I) wherein R is C1-6alkylor C5-10aryl-C1-6alkyl, comprising the steps of: a) reacting isonicotinohydrazide and methyl isothiocyanate, thereby obtaining 2-isoni-cotinoyl-N-methylhydrazinecarbothioamide; b) under alkaline conditions allowing said 2-isonicotinoyl-N-methylhydrazinecar-bothioamide to undergo a ring-forming reaction, thereby obtaining 4-methyl-5-pyridin-4-yl-2,4-dihydro-3H-1,2,4-triazole-3--thione; and c) under alkaline conditions allowing said 4-methyl-5-pyridin-4-yl-2,4-dihydro-3H-1,2,4-triazole-3-thione to react with R-X, wherein R has the same meaning as in formula I and X is selected from the group of Cl, Br and I, thereby obtaining a compound according to formula I; wherein steps a), b) and c) are carried out in an aqueous environment without intermediate iso-lations. |
