Procedure

Intermediate 17b (234 mg, 0.66 mmol) was dissolved in 1,4-dioxane (7.0 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; 268 mg, 0.66 mmol) and diisopropylethylamine (229 μL, 1.32 mmol) were added. The reaction mixture was heated to 60° C. for 20 h, then cooled, 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, to give the title compound (120 mg, 0.20 mmol, 30%). LCMS (Method 5): Rt 4.76 min, m/z=609 [MH+]. 1H NMR (400 MHz, d4-MeOD): 1.30 (9H, s), 1.85-2.05 (2H, m), 2.05-2.18 (2H, m), 2.38 (3H, s), 3.57-3.76 (8H, br m), 4.86-4.92 (1H, dd, J 8.6, 5.5 Hz), 5.54-5.57 (1H, t, J 4.3 Hz), 6.33 (1H, s), 7.20-7.34 (9H, m), 7.58-7.65 (2H, m), 8.24-8.26 (1H, dd, J 2.4, 0.8 Hz).
