3-(3-Chloro-4-cyanophenoxy)-2-hydroxy-2-methyl-N-(2-methyl-4-nitrophenyl)propionamide was prepared as described in Example 64c starting from 2-chloro-4-hydroxybenzonitrile and 2-methyloxirane-2-carboxylic acid (2-methyl-4-nitrophenyl)amide. The crude product was purified by flash chromatography (dichloromethane-1.3% methanol). 1H NMR (400 MHz, DMSO-d6): 1.46 (3H, s), 2.37 (3H, s), 4.15 (1H, d, J=10.1 Hz), 4.39 (1H, d, J=10.1 Hz), 6.51 (1H, s), 7.10 (1H, dd, J=8.8 Hz, J=2.4 Hz), 7.37 (1H, d, J=2.4 Hz), 7.86 (1H, d, J=8.8 Hz), 8.05-8.12 (2H, m), 8.18 (1H, d, J=2.3 Hz), 9.56 (1H, s).
