Procedure

To a solution of (S)-4-methyl-2-(2-oxo-4-o-tolyloxy-2,5-dihydro-pyrrol-1-yl)-pentanoic acid (prepared as in Example 120, 0.228 g, 0.75 mmol) in N,N-dimethylformamide (4 mL) was added 1-((R)-2,2-dimethyl-[1,3]dioxolan-4-yl-methyl)-1H-pyrazol-3-ylamine (prepared as in Example 49, 0.192 g, 0.97 mmol) and benzotriazol-1-yl-oxy-tris(dimethylamino)phosphonium hexafluorophosphate (0.663 g, 1.50 mmol). The mixture was stirred at 0° C. and triethylamine (0.153 g, 1.51 mmol) was added. The mixture was stirred at room temperature for 4 h 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 25 g, 30% to 70% ethyl acetate/hexanes) which afforded (S)-4-methyl-2-(2-oxo-4-o-tolyloxy-2,5-dihydro-pyrrol-1-yl)-pentanoic acid [1-((R)-2,2-dimethyl-[1,3]dioxolan-4-yl-methyl)-1H-pyrazol-3-yl]-amide (0.175 g, 48%) as a pink solid: HR-ES-MS m/z calculated for C26H34N4O5 [M+H]+ 483.2602, observed 483.2603, 1H NMR (200 MHz, DMSO-d6) δ ppm 1.00 0.90 (d, J=6.5 Hz, 3H), 0.94 (d, J=6.5 Hz, 3H), 1.25 (s, 3H), 1.30 (s, 3H), 1.36-1.66 (m, 2H), 1.68-1.81 (m, 1H), 2.19 (s, 3H), 3.73 (dd, J=8.5, 5.7 Hz, 1H), 4.00 (dd, J=8.5, 6.3 Hz, 1H), 4.11 (t, J=5.7 Hz, 2H), 4.20 (d, J=18.4 Hz, 1H), 4.28-4.42 (m, 1H), 4.58 (d, J=18.4 Hz, 1H), 4.63 (s, 1H), 4.88 (dd, J=10.6, 4.8 Hz, 1H), 6.44 (d, J=2.4 Hz, 1H), 7.16-7.33 (m, 3H), 7.36 (d, J=7.5 Hz, 1H), 7.60 (d, J=2.4 Hz, 1H), 10.80 (s, 1H).
