USE: A herbicide capable of controlling harmful weeds, e.g., baruyard grass, chufa, toothcup, bulrush, etc. without damaging practically a crop, e.g., a rice plant.
PROCESS: A compound shown by the formula II is reacted with 2,3-dinitrobenzene in the presence of an alkali compound to give the desired compound shown by the formula I. The presence of a catalyst of a cuprous halide, e.g., cuprous iodide and cuprous fluoride in the reaction improves reactivity.
