Procedure

To a solution of Intermediate 62c (140 mg, 0.37 mmol) in 1,4-dioxane (4.00 mL) was added DIPEA (129 μL, 0.74 mmol) 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; 150 mg, 0.37 mmol). The reaction was heated to 60° C. overnight then cooled and partitioned between EtOAc and water. The aqueous layer was then extracted with EtOAc (3×). The combined organic layers were washed with brine, dried (MgSO4), filtered and evaporated in vacuo. The residue was purified by FCC, using 0-7.5% MeOH in DCM. Further purification by HPLC (C18 X-select column, 10-98% MeCN in H2O, 0.1% HCO2H) gave the title compound as a white powder after freeze-drying (73 mg, 31%). LCMS (Method 5): Rt 3.75 min, m/z 633.2 [MH+]. 1H NMR (400 MHz, d4-MeOD): 1.30 (9H, s), 1.45 (1H, m), 1.60-1.83 (3H, m), 1.83-1.93 (2H, m), 1.93-2.07 (5H, m), 2.11 (1H, m), 2.20-2.33 (2H, m), 2.38 (3H, s), 3.05 (1H, dt, J 11.8, 2.8), 3.79 (1H, dd, J 10.9, 2.8), 4.91 (1H, dd, J 9.0, 5.7), 5.32 (1H, t, J 4.0), 6.33 (1H, s), 7.19-7.36 (9H, m), 7.64 (1H, d, J 10.0), 8.43 (1H, d, J 1.7).
