Procedure

To a solution of Intermediate 61c (72.0 mg, 0.19 mmol) in 1,4-dioxane (2.00 mL) was added DIPEA (66 μL, 0.38 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; 77.0 mg, 0.19 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, 20-70% MeCN in H2O, 0.1% HCO2H) gave the title compound as a white powder after freeze-drying (37 mg, 31%). LCMS (Method 5): Rt 3.73 min, m/z 633.2 [MH+]. 1H NMR (400 MHz, d4-MeOD): 0.94 (3H, t, J 7.2), 1.30 (9H, s), 1.89-2.16 (6H, m), 2.22-2.31 (2H, m), 2.31-2.38 (2H, m), 2.38 (3H, s), 2.49 (1H, m), 3.32 (1H, m), 4.11 (1H, t, J 8.0), 4.90 (1H, dd, J 9.0, 5.6), 5.28 (1H, t, J 4.1), 6.33 (1H, s), 7.19-7.36 (9H, m), 7.65 (1H, dd, J 10.0, 0.7), 8.37 (1H, d, J 1.9).
