Reaction Steps

To (S)-N-(1-(1H-imidazol-2-yl)-2-phenylethyl)-2-(3-(trifluoromethyl)-4,5,6,7-tetrahydro-1H-indazol-1-yl)acetamide (111 mg, 0.27 mmol) in NMP (0.6 mL) was added iodobenzene (27 μL, 0.24 mmol), Cu2O (1 mg), PEG 3500 (50 mg), 4,7-dimethoxy-1,10-phenanthroline (6 mg) and Cs2CO3 (110 mg, 0.34 mmol). The reaction was heated to 115° C. for 4 hr. After cooling to ambient temperature, the reaction mixture was filtered over a heavy metal scavenging column and eluted with DCM. The solvents were removed in vacuo and the residue purified by RP HPLC to provide the title compound: 1H NMR (400 MHz, DMSO-d6) δ 9.16 (s), 7.55 (s, 1H), 7.42 (t, 1H), 7.14 (q, 2H), 7.01 (d, 1H), 6.84 (dd, 1H), 4.77-4.71 (m, 1H), 3.08 (d, 1H), 2.36 (s, 1H), 1.62 (d, 2H). MS (m/z) 494.3 [M+H]+.
