To a solution of (S)-2-{4-[2-fluoro-3-(1-hydroxy-1-methyl-ethyl)-phenoxy]-2-oxo-2,5-dihydro-pyrrol-1-yl}-4-methyl-pentanoic acid (0.392 g, 1.07 mmol) in dichloromethane (10 mL) was added 1-methyl-1H-pyrazol-3-ylamine (0.208 g, 2.14 mmol) and benzotriazol-1-yl-oxy-tris(dimethylamino)phosphonium hexafluorophosphate (0.522 g, 1.18 mmol). The mixture was stirred at 0° C. and N,N-diisopropylethylamine (0.304 g, 2.35 mmol) was added. The mixture was stirred at room temperature overnight and the solvents were evaporated. The residue was treated with ethyl acetate and ammonium chloride solution, and the organic layer separated. The organic layer was washed with brine and dried over sodium sulfate. The solvents were evaporated and the residue was purified by ISCO flash chromatography (Teledyne Isco RediSep Flash Column 112 g, 60% to 100% ethyl acetate/hexanes) which afforded (S)-2-{4-[2-fluoro-3-(1-hydroxy-1-methyl-ethyl)-phenoxy]-2-oxo-2,5-dihydro-pyrrol-1-yl}-4-methyl-pentanoic acid (1-methyl-1H-pyrazol-3-yl)-amide (0.441 g, 92%) as an off-white solid: HR-ES-MS m/z calculated for C23H29FN4O4 [M+H]+ 445.2246, observed 445.2246, 1H NMR (300 MHz, DMSO-d6) δ 1.00 0.90 (d, J=6.4 Hz, 3H), 0.93 (d, J=6.4 Hz, 3H), 1.36-1.47 (m, 1H), 1.49 (s, 6H), 1.52-1.65 (m, 1H), 1.67-1.82 (m, 1H), 3.73 (s, 3H), 4.20 (d, J=18.4 Hz, 1H), 4.58 (d, J=18.4 Hz, 1H), 4.81 (s, 1H), 4.88 (dd, J=10.7, 5.0 Hz, 1H), 5.42 (s, 1H), 6.40 (d, J=2.1 Hz, 1H), 7.23 (t, J=7.8 Hz, 1H), 7.29-7.40 (m, 1H), 7.54 (d, J=2.1 Hz, 1H), 7.51-7.60 (m, 1H), 10.73 (s, 1H).
