Reaction Steps

3-(4-Fluoro-3-trifluoromethylphenoxy)-2-hydroxy-2-methyl-N-(3-methyl-4-nitrophenyl)propionamide was prepared as described in Example 1 starting from 4-fluoro-3-(trifluoromethyl)phenol and 2-methyloxirane-2-carboxylic acid (3-methyl-4-nitrophenyl)amide. The crude product was purified by flash chromatography (dichloromethane-1% methanol). 1H NMR (400 MHz, DMSO-d6): 1.44 (3H, s), 2.53 (3H, s), 4.06 (1H, d, J=9.9 Hz), 4.32 (1H, d, J=9.9 Hz), 6.23 (1H, s), 7.24-7.31 (2H, m), 7.38-7.43 (1H, m), 7.87 (1H, dd, J=9.0 Hz, J=2.1 Hz), 7.91 (1H, d, J=2.0 Hz), 8.03 (1H, d, J=9.0 Hz), 10.14 (1H, s).
