A mixture of 3-bromo-1-[1-(4-chlorophenyl)-5-isopropylpyrazol-4-yl]pyrrolidin-2-one (0.200 g, 0.52 mmol), 2-ethyl-4-(trifluoromethyl)-1H-imidazole (0.060 g, 0.36 mmol) and K2CO3 (0.080 g, 0.58 mmol) in DMF (1.5 mL) was stirred at 65° C. for 1.5 hrs. The mixture was then cooled to room temperature, quenched with water (30 mL), extracted with EtOAc (50 mL), and purified by reverse phase HPLC (C18 column, acetonitrile-H2O with 0.1% TFA as eluent) to yield the title compound (0.0022 g, TFA salt, 1.0%). 1H NMR (TFA salt) (400 MHz, CDCl3) δ 7.58 (s, 1H), 7.49 (m, 2H), 7.35 (m, 2H), 7.21 (s, 1H), 5.03 (dd, J=10.4, 8.8 Hz, 1H), 3.88 (m, 1H), 3.81 (m, 1H), 3.03 (heptet, J=7.0 Hz, 1H), 2.88 (m, 2H), 2.30 (m, 2H), 1.40 (t, J=7.4 Hz, 3H), 1.23 (m, 6H); MS: (ES) m/z calculated for C22H23ClF3N5O [M+H]+ 466.1. found 466.1.
