Procedure
A brown solution of (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; 227 mg, 0.560 mmol), Intermediate 90e (145 mg, 0.400 mmol) and DIPEA (0.111 mL, 0.640 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 gave a brown solid. FCC, using 2-7% [2M NH3 in MeOH] in DCM, gave a pale brown solid (195 mg). Further purification by MDAP (Method 8) gave the title compound as a white powder after freeze-drying (10.0 mg, 4%). LCMS (Method 5): Rt 3.62 min, m/z 619 [MH+]. 1H NMR (400 MHz, d6-DMSO): 1.27 (9H, s), 1.83-1.98 (2H, m), 2.08-2.20 (3H, m), 2.32 (3H, s), 2.33-2.40 (1H, m), 2.36 (3H, s), 2.59-2.70 (2H, m), 2.75 (1H, dd, J 9.2, 6.1), 2.96 (1H, t, J 8.7), 3.93-4.01 (1H, m), 4.83 (1H, td, J 8.4, 5.4), 5.46 (1H, t, J 4.6), 6.32 (1H, s), 7.10 (1H, d, J 8.5), 7.18 (1H, dd, J 9.9, 2.1), 7.27-7.40 (8H, m), 7.69 (1H, dd, J 9.9, 0.8), 8.04 (1H, s), 8.44 (1H, d, J 2.0).
