Procedure
A mixture of Intermediate 55a (120 mg, 0.33 mmol), (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; 147 mg, 0.36 mmol), DIPEA (86.0 μL, 0.50 mmol) and 1,4-dioxane (2.5 mL) were heated to 60° C. for 18 h. After cooling the solvent was evaporated in vacuo. The residue was purified by FCC, using 0-10% MeOH in DCM, to give a pale yellow foam. This was lyophilised to provide the title compound as an off-white solid (28 mg, 20%). LCMS (Method 5) Rt 4.76 min, m/z 619 [MH+]. 1H NMR (400 MHz, d6-DMSO): 1.26 (9H, s), 1.61 (2H, m), 1.72 (5H, m), 2.02-2.17 (3H, m), 2.35 (3H, s), 3.13 (4H, m), 4.90 (1H, m), 5.58 (1H, m), 6.31 (1H, s), 6.99 (1H, d, J 7.8), 7.19 (1H, dd, J 9.7, 2.2), 7.26-7.43 (8H, m), 7.58-7.64 (2H, m), 7.98 (1H, s).
