Synthesis of 2-(2-Chloro-benzyl)-2-(1-chloro-cyclopropyl)oxirane |

| Abstract: | An improved method for synthesis of 2-(2-chloro-benzyl)-2-(1-chloro-cyclopropyl)oxirane, an important intermediate for producing prothioconazole, was studied. Thus, 1-chloro-N,N-dimethylcyclopropanecarboxamide and 2-chlorobenzyl chloride were subjected to a Grignard reaction to prepare 2-chlorobenzyl-(1-chloro-cyclopropyl)ketone, which was further reacted with sulfur ylide to give the corresponding oxirane. |
