Reaction Steps

3-(4-Fluorophenoxy)-2-hydroxy-2-methyl-N-(2-methyl-3-nitrophenyl)propionamide was prepared as described in Example 1c starting from 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), 2.28 (3H, s), 3.96 (1H, d, J=9.5 Hz), 4.17 (1H, d, J=9.5 Hz), 6.14 (1H, s), 6.93-6.97 (2H, m), 7.08-7.13 (2H, m), 7.41-7.45 (1H, m), 7.66-7.68 (1H, m), 7.72-7.75 (1H, m), 9.72 (1H, s).
