Abstract

PURPOSE: To obtain the title compound useful as a herbicide in high yields without using henzoylchloride, by reacting a pyrazolone derivative with a free benzoic acid under a specific condition so that the 4-position of the compound is acylated.
CONSTITUTION: A pyrazolone derivative shown by the formula I (R1 is lower alkyl or lower alkenyl; R2 is lower alkyl) is reacted with a benzoic acid shown by the formula II (X is halogen, lower alkyl, lower alkoxy, cyano, trifluoromethyl, or nitro; n is 1W3) in an inert solvent in the presence of an organic dehydrating condensing agent, e.g., carbodiimide, and a basic salt of an alkali metal or a hydroxide of an alkaline earth metal or a basic salt at 40W120°C, preferably 50W70°C, for 30 minutes to 2 hours to give the desired compound, e.g., 1,3-dimethyl-4-(2,4-dichlorobenzoyl)-5-hydroxypyrazole, shown by the formula III.
