Abstract
PURPOSE: A 2-nitrobenzonitrile derivative is made to react with a halide of alkaline metal or a mixture thereof with a lithium halide in an aprotonic polar solvent, thus producing title compound used as an agricultural chemical inexpensively through shortened stages.
CONSTITUTION: A compound of formula I (X is halogen; n is 1, 2) is made to react with a halide of alkaline earth metal or a mixture thereof with a lithium halide or a mixture of a halide of alkaline earth metal with an anhydrous aluminum halide or said mixture thereof further with a lithium halide in an aprotonic polar solvent such as DMF or DMSO to give title compound of formula II. In these compounds, the halogen atoms are required to be the same. The starting materials are inexpensive and the waste water and refuse formed during the reaction are very little. The coexistence of anhydrous aluminum halide remarkably increases the yield.
