No. 8,426,443 was added with nitrogen. Under an atmosphere, a mixture of 42.2 g of pyridine-2-carbonyl chloride and 206 g of toluene was added dropwise at 40 ° C., and the mixture was stirred at 40 ° C. for 3 hours. 88.8 g of an 8% aqueous sodium hydroxide solution was added to the obtained mixture, and the mixture was cooled to 5 ° C.
• Test example 1 After dispensing 1 ⁇ L of a dimethyl sulfoxide solution containing a predetermined concentration of compound A into wells of a titer plate (96 wells), 150 ⁇ L of a complete medium containing a spore suspension of Botrytis cinerea was dispensed. Was adjusted to have a final concentration of 100 ppm, which was treated. A non-treated section was prepared in another well. After the plate was cultured at 18 ° C. for 3 days to grow the fungus, the absorbance at 600 nm of each well of the titer plate was measured to determine the growth of the fungus.
