Procedure

Intermediate 14c (120 mg, 0.31 mmol) was dissolved in 1,4-dioxane (2.0 mL) and [5-tert-butyl-2-p-tolyl-2H-pyrazol-3-yl]-carbamic acid 2,2,2-trichloro-ethyl ester (Synthetic Communications, 2009, 39, 3999-4009, which is incorporated herein by reference in its entirety; 124 mg, 0.31 mmol) and diisopropylethylamine (106 μL, 0.61 mmol) were added. The reaction was heated to 60° C. for 20 h. After cooling, the mixture was partitioned between EtOAc (50 mL) and water (50 mL), and extracted into EtOAc (3×). The combined organic layers were washed with brine, dried (MgSO4) and evaporated in vacuo. The residue was purified by FCC, using 0-10% [2M NH3 in MeOH] in DCM, then further purified by HPLC (C18 X-select column, 20-70% MeCN in H2O, 0.1% formic acid) to give the title compound as the formic acid salt (103 mg, 0.16 mmol, 52%). LCMS (Method 5): Rt 3.63 min, m/z=648 [MH+]. 1H NMR (400 MHz, d4-MeOD): 1.30 (9H, s), 1.90-1.99 (1H, m), 1.99-2.07 (1H, m), 2.10-2.19 (1H, m), 2.21-2.30 (1H, m), 2.37 (3H, s), 2.38 (3H, s), 2.52-2.67 (8H, br s), 4.05-4.09 (1H, d, J 14.3 Hz), 4.11-4.15 (1H, d, J 14.3 Hz), 4.88-4.93 (1H, dd, J 8.9, 5.6 Hz), 5.41-5.44 (1H, t, J 4.3 Hz), 6.33 (1H, s), 7.22-7.36 (11H, m), 7.63-7.67 (1H, d, J 10.0 Hz), 8.21-8.22 (1H, d, J 1.9 Hz), 8.44-8.45 (0.25H, s).
