Participants

Reaction Steps

Into a 1-neck round-bottom flask was added 4-[5-(1-cyclopentyl-3-ethyl-1H-indazol-6-yl)-1H-pyrazol-1-yl]benzoic acid (50.0 mg, 0.125 mmol), 2 mL of N,N-dimethylformamide, diethylamine (0.00913 g, 0.125 mmol), HATU (47.4 mg, 0.125 mmol) and N,N-diisopropylethylamine (43.5 uL, 0.250 mmol). The reaction was stirred for 3 days at room temperature, concentrated under reduced pressure, and purified by preparative HPLC (UV detection) to give 33 mg (0.0725 mmol, 58%) of 4-[5-(1-cyclopentyl-3-ethyl-1H-indazol-6-yl)-1H-pyrazol-1-yl]-N,N-diethylbenzamide as a clear oil. LC/MS (EI) tR 5.26 (Method C), m/z 456.1 (M++1). 1H NMR (CDCl3 300 MHz) δ 1.0-1.2 (m, 5H); 1.3 (t, 3H); 1.7-1.9 (m, 5H); 2.0 (m, 4H); 3.0 (q, 2H); 3.1 (br s, 2H); 3.4 (br s, 2H); 4.8 (m, 1H); 6.6 (s, 1H); 6.9 (d, 1H); 7.2 (m, 5H); 7.5 (d, 1H); 7.7 (s, 1H).
