50.5 g (0.5 mol) of triethylamine were added dropwise to 123 g (0.5 mol) of crude 1-bromo-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-butan-2-one and 65 g (0.5 mol) of 6-chloro-2-hydroxy-pyridine in 250 ml of absolute acetonitrile at 24° to 30° C., while stirring. The mixture was stirred at room temperature for 3 hours and filtered and the filtrate was concentrated in vacuo. After treatment with water, the residue crystallized out. 76.6 g (52% of theory) of 1-(6-chloropyridin-2-yl-oxy)-3,3-dimethyl-1-(1,2,4-triazol-1-yl)-butan-2-one of melting point 103°-105° C. were obtained.
