To a solution of (S)-2-[4-(3-dimethylamino-2-fluoro-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-4-methyl-pentanoic acid lithium salt (0.257 g, 0.73 mmol) in N,N-dimethylformamide (5 mL) was added 1-((R)-2,2-dimethyl-[1,3]dioxolan-4-yl-methyl)-1H-pyrazol-3-ylamine (prepared as in Example 49, 0.160 g, 0.81 mmol) and benzotriazol-1-yl-oxy-tris(dimethylamino)phosphonium hexafluorophosphate (1.91 g, 4.32 mmol). 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 a saturated sodium chloride solution and dried over sodium sulfate. The solvents were evaporated and the residue was purified by ISCO flash chromatography (Teledyne Isco RediSep Flash Column 25 g, 10% to 75% ethyl acetate/hexanes) which afforded (S)-2-[4-(3-dimethylamino-2-fluoro-phenoxy)-2-oxo-2,5-dihydro-pyrrol-1-yl]-4-methyl-pentanoic acid [1-((R)-2,2-dimethyl-[1,3]dioxolan-4-yl-methyl)-1H-pyrazol-3-yl]-amide (0.200 g, 51%) as a yellow solid: HR-ES-MS m/z calculated for C27H36FN5O5 [M+H]+ 530.2773, observed 530.2771, 1H NMR (300 MHz, DMSO-d6) δ ppm 1.00 0.90 (d, J=6.3 Hz, 3H), 0.94 (d, J=6.3 Hz, 3H), 1.25 (s, 3H), 1.31 (d, J=3.0 Hz, 3H), 1.38-1.50 (m, 1H), 1.50-1.65 (m, 1H), 1.69-1.85 (m, 1H), 2.82 (s, 6H), 3.74 (dd, J=8.3, 5.9 Hz, 1H), 4.01 (dd, J=8.5, 6.3 Hz, 1H), 4.04-4.15 (m, 2H), 4.20 (d, J=18.4 Hz, 1H), 4.29-4.43 (m, 1H), 4.58 (d, J=18.4 Hz, 1H), 4.86 (s, 1H), 4.87-4.95 (m, 1H), 6.44 (d, J=2.1 Hz, 1H), 6.79-6.98 (m, 2H), 7.12 (t, J=8.5 Hz, 1H), 7.61 (br. s., 1H), 10.80 (s, 1H).
