Versuchsvorschrift

Intermediate 14c (120 mg, 0.31 mmol) was dissolved in 1,4-dioxane (2.0 mL) and [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; 124 mg, 0.31 mmol) and diisopropylethylamine (106 μL, 0.61 mmol) were added. The reaction was heated to 60° C. for 20 h. After cooling, the mixture was partitioned between EtOAc (50 mL) and water (50 mL), and extracted into EtOAc (3 x). The combined organic layers were washed with brine, dried (MgSO4) and evaporated in vacuo. The residue was purified by FCC, using 0-10% [2M NH3 in MeOH] in DCM, then further purified by HPLC (C18X-select column, 20-70% MeCN in H2O, 0.1% formic acid) to give the title compound as the formic acid salt (103 mg, 0.16 mmol, 52%). LCMS (Method 5): Rt 3.63 min, m/z=648 [MH+]. 1H NMR (400 MHz, d4-MeOD): 1.30 (9H, s), 1.90-1.99 (1H, m), 1.99-2.07 (1H, m), 2.10-2.19 (1H, m), 2.21-2.30 (1H, m), 2.37 (3H, s), 2.38 (3H, s), 2.52-2.67 (8H, br s), 4.05-4.09 (1H, d, J=14.3 Hz), 4.11-4.15 (1H, d, J=14.3 Hz), 4.88-4.93 (1H, dd, J 8.9, 5.6 Hz), 5.41-5.44 (1H, t, J=4.3 Hz), 6.33 (1H, s), 7.22-7.36 (11H, m), 7.63-7.67 (1H, d, J=10.0 Hz), 8.21-8.22 (1H, d, J=1.9 Hz), 8.44-8.45 (0.25H, s).
