Procedure

An orange-brown solution (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; 243 mg, 0.600 mmol), Intermediate 88e (151 mg, 0.400 mmol) and DIPEA (0.122 mL, 0.700 mmol) in dry dioxane (5 mL) was stirred at 65° C. for 15 h. The cooled solution was concentrated in vacuo, redissolved in MeOH (2 mL), applied to an SCX-2 cartridge (10 g) and washed with MeOH (50 mL). The product was eluted with 2M NH3 in MeOH (30 mL); concentration in vacuo left a brown solid. FCC, using 2-7% [2M NH3 in MeOH] in DCM, gave the title compound as a pale yellow solid (188 mg, 74%). LCMS (Method 5): Rt 3.63 min, m/z 633 [MH+]. 1H NMR (400 MHz, d6-DMSO): 1.27 (9H, s), 1.55 (1H, qd, J 11.9, 5.3), 1.68-1.79 (2H, m), 1.83-2.03 (4H, m), 2.06-2.14 (2H, m), 2.22 (1H, t, J 10.9), 2.22 (3H, s), 2.36 (3H, s), 2.83 (1H, br d, J 10.9), 3.01 (1H, ddd, J 11.1, 3.6, 1.6), 3.54 (1H, tt, J 11.1, 3.7), 4.83 (1H, td, J 8.4, 5.5), 5.57 (1H, t, J 4.5), 6.33 (1H, s), 7.09 (1H, d, J 8.5), 7.15 (1H, dd, J 9.8, 2.0), 7.27-7.42 (8H, m), 7.68 (1H, d, J 9.9), 8.03 (1H, s), 8.32 (1H, d, J 2.0).
