Reaction Steps

Ethyl 4-[(1S)-1-(3-[2-fluoro-5-(trifluoromethyl)phenyl]-5-{[(trifluoromethyl)sulfonyl]oxy}-1H-pyrazol-1-yl)ethyl]benzoate (1.05 g, 1.90 mmol), 6-methoxy-2-naphthylboronic acid (0.43 g, 2.1 mmol), and triethylamine (0.53 ml, 3.8 mmol) were dissolved in DME (20 ml). After deoxygenation (vacuum-N2 cycles) Pd(PPh3)4 (85 mg, 4% mol) was added. The mixture was deoxygenated again and heated in microwave reactor to 100° C. for 15 min. The reaction mixture was filtered through a Celite pad, concentrated and purified by flash column chromatography (SiO2, 5-20% ethyl acetate in hexane gradient) to give ethyl 4-{(1S)-1-[3-[2-fluoro-5-(trifluoromethyl)phenyl]-5-(6-methoxy-2-naphthyl)-1H-pyrazol-1-yl]ethyl}benzoate as colorless gel. NMR (500 MHz, CDCl3) δ: 1.38 (t, J=7.1 Hz, 3H); 1.99 (d, J=7.1 Hz, 3H); 3.96 (s, 3H); 4.37 (q, J=7.1 Hz, 2H); 5.64 (q, J=7.1 Hz, 1H); 6.87 (d, JF-H=4.2 Hz, 1H); 7.17 (d, J=2.5 Hz, 1H); 7.20 (dd, J=2.5 Hz, 8.9 Hz, 1H); 7.25 (t, J=9.5 Hz, 1H); 7.30 (d, J=8.4 Hz, 2H); 7.32 (dd, J=1.5 Hz, 8.4 Hz, 1H); 7.56 (m, 1H); 7.66 (d, J=1.5 Hz, 1H); 7.68 (d, J=8.9 Hz, 1H); 7.77 (d, J=8.4 Hz, 1H); 8.00 (d, J=8.4 Hz, 2H); 8.48 (dd, J=2.7 Hz, 6.8 Hz, 1H). MS C32H26F4N2O3 Cald: 562.19; Obsd (M+1): 563.33.
