Procedure
To a solution of Intermediate 10d (204 mg, 0.62 mmol) and DIPEA (0.127 mL, 0.80 mmol) in 1,4-dioxane (6 mL), (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; 315 mg, 0.78 mmol) was added. The mixture was heated at 80° C. under argon for 17 h, and then evaporated to dryness. The residue was purified by FCC, eluting with 0-100% ethyl acetate in cyclohexane, to give the slightly impure product (0.262 g). Further purification by HPLC (Method 6) gave the title compound as a white solid (102 mg, 28%). LCMS (Method 5): Rt 4.51 min, m/z 583 [MH+]. 1H NMR (400 MHz, d6-DMSO): 1.26 (9H, s), 1.69-1.81 (1H, m), 1.90-2.24 (3H, m), 2.36 (3H, s), 3.36 (3H, s), 4.05 (2H, s), 4.86-4.94 (1H, m), 5.62-5.67 (1H, m), 6.32 (1H, s), 6.91 (1H, dd, J 2.5, 5.9), 7.03 (1H, d, J 8.4), 7.26-7.37 (8H, m), 7.60 (1H, br d, J 2.0), 8.01 (1H, s), 8.16 (1H, d, J 5.7), 9.90 (1H, s).
