3-(3-Chloro-4-fluorophenoxy)-2-hydroxy-2-methyl-N-(2-methyl-3-nitrophenyl)propionamide was prepared as described in Example 1 starting from 3-chloro-4-fluorophenol and 2-methyloxirane-2-carboxylic acid (2-methyl-3-nitrophenyl)amide. The crude product was purified by flash chromatography (dichloromethane-1% methanol). 1H NMR (400 MHz, DMSO-d6): 1.44 (3H, s), 2.27 (3H, s), 3.99 (1H, d, J=9.8 Hz), 4.23 (1H, d, J=9.8 Hz), 6.15 (1H, s), 6.92-6.97 (1H, m), 7.17-7.20 (1H, m), 7.29-7.35 (1H, m), 7.41-7.46 (1H, m), 7.66-7.69 (1H, m), 7.72-7.75 (1H, m), 9.72 (1H, s).
