A mixture of N-(2-bromo-benzyl)-2,2,2-trifluoro-acetamide (282 mg, 1.0 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (284 mg, 1.3 mmol), Pd(OAc)2 (20 mg, 0.09 mmol) and PS—PPh3 (40 mg, 3 mmol/g, 0.12 mmol) was dissolved in DMF (5 mL) and 4M K2CO3 solution (0.5 mL) was added. The reaction was heated at 80° C. overnight. The mixture was filtered, concentrated and purified by column chromatography (0-50% ethyl acetate-hexanes) to yield N-(4′-amino-biphenyl-2-ylmethyl)-2,2,2-trifluoro-acetamide (1-1) (143 mg, 49%). HPLC ret. time 1.90 min, 10-99% CH3CN, 5 min run; ESI-MS 295.5 m/z (MH+).
