To a vial containing the title compound of Example 1 Step B (3.0 g, 11.36 mmol), were added 3-iodobenzotrifluoride (1.97 mL, 13.6 mmol), copper iodide (218 mg, 1.14 mmol), potassium phosphate (5.05 g, 23.9 mmol), and 1,2-trans-N,N-dimethylcyclohexane diamine (0.718 mL, 4.54 mmol). The reaction mixture was placed under a nitrogen atmosphere, and anhydrous toluene (11.4 mL, deoxygenated via nitrogen sparge) was added. The vial was then capped and placed in a pre-heated oil bath (110° C.) and stirred rapidly for 19 h. The mixture was allowed to cool to room temperature, then was filtered. The supernatant was washed extensively with EtOAc, and the organic phase was concentrated in vacuo. Purification by flash chromatography (10% EtOAc in hexanes) afforded the title compound: LCMS B, tr=3.02 min, m/z 408.2 [M+H]+; 1H NMR (500 MHz, CDCl3) δ 7.74-7.72 (m, 2H), 7.64 (t, J=8.0 Hz, 1H), 7.52 (s, 1H), 7.46 (d, J=8.0 Hz, 1H), 7.37 (s, 1H), 7.26 (dd, J=9.0, 2.0 Hz, 1H), 6.96 (d, J=9.0 Hz, 1H), 2.94 (t, J=7.5 Hz, 2H), 1.68 (quint., J=7.5 Hz, 2H), 1.38-1.28 (m, 6H), 0.88 (t, J=7.0 Hz, 3H).
