Procedure

A solution of Intermediate 87d (150 mg, 0.383 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; 232 mg, 0.575 mmol) and DIPEA (198 mg, 1.53 mmol) in DMF (4 mL) was stirred at 50° C. for 1 h. The cooled reaction mixture was applied to an SCX-2 cartridge (10 g) and washed with MeOH. The product was eluted with 2M NH3 in MeOH; concentration in vacuo gave a residue. FCC, using 0-6% [2M NH3 in MeOH] in DCM, then trituration with diethyl ether gave the title compound as an off-white powder (170 mg, 68%). LCMS (Method 5): Rt 3.80 min, m/z 647.5 [MH+]. 1H NMR (400 MHz, d4-MeOH): 1.15 (3H, s), 1.24 (3H, s), 1.30 (9H, s), 1.85-2.05 (4H, m), 2.14 (3H, s), 2.19-2.31 (2H, m), 2.38 (3H, s), 2.97 (1H, d, J 10.3), 3.45 (1H, dd, J 7.5, 6.1), 4.06 (1H, t, J 9.3), 4.90 (1H, m), 5.30 (1H, t, J 4.2), 6.33 (1H, s), 7.20-7.36 (9H, m), 7.65 (1H, d, J 10.8), 8.46 (1H, d, J 1.1).
