Reaction Steps

A mixture of 0.7 g (0.0023 mole) of 1-(4-chloro-2-fluoro-5-hydroxyphenyl)-3-difluoromethyl-4,5-dihydro-4-methyl-1,2,4-triazol-5(1H)-one, 0.9 g (0.0067 mole) of potassium carbonate, and 0.6 g (0.0027 mole) of tert-butyl 2-bromopropionate in 40 mL of acetone was stirred at room temperature for approximately 72 hours. The reaction mixture was partitioned between water and methylene chloride and the organic phase was washed with water. After drying over anhydrous magnesium sulfate the organic phase was filtered. Evaporation of the filtrate under reduced pressure yielded 0.9 g of tert-butyl 2-[2-chloro-4-fluoro-5-(3-difluoromethyl-4,5-dihydro-4-methyl-5-oxo-1H-1,2,4-triazol-1-yl)phenoxy]propionate as an oil, Compound 40.
