反応手順

2-Hydroxy-3-(4-methoxy-3-trifluoromethylphenylamino)-2-methyl-N-(3-methyl-4-nitrophenyl)propionamide was prepared as described in Example 52 starting from 3-amino-6-methoxybenzotrifluoride and 2-methyloxirane-2-carboxylic acid (3-methyl-4-nitrophenyl)amide. The crude product was purified by flash chromatography (dichloromethane-1.5% methanol). 1H NMR (400 MHz, DMSO-d6): 1.41 (3H, s), 2.51 (3H, s), 3.12 (1H, dd, J=13.0 Hz, J=4.8 Hz), 3.45 (1H, dd, J=13.0 Hz, J=7.7 Hz), 3.71 (3H, s), 5.42 (1H, m), 6.00 (1H, s), 6.88 (1H, dd, J=8.9 Hz, J=2.7 Hz), 6.92 (1H, d, J=2.7 Hz), 6.97 (1H, d, J=8.9 Hz), 7.78 (1H, dd, J=8.9 Hz, J=2.3 Hz), 7.81 (1H, d, J=1.9 Hz), 8.00 (1H, d, J=8.9 Hz), 9.98 (1H, s).
