Procedure

To a slurry of 2-(5-(diethylamino)-2-(3-iodobenzamido)phenyl)-N-(3-(trifluoromethyl)benzyl)isonicotinamide (385 mg, 0.57 mmol), 3,6,9,12-tetraoxapentadec-14-yn-1-ol (175 mg, 0.75 mmol), Et3N (3 mL) and THF (2 mL) was added bis(triphenylphosphine)palladium(II)dichloride (12 mg, 0.017 mmol) and CuI (10 mg, 0.053 mmol) and purged well with nitrogen. The reaction mixture was stirred for 13 hours, then concentrated under vacuum and combined with the crude product from another run (0.15 mmol scale). Purification by flash chromatography on silica gel eluting (1% to 5% MeOH in DCM) gave the title compound (349 mg). 1H NMR (400 MHz, CDCl3, ppm) δ□ 12.51 (s, 1H), 8.83 (d, J=5.3 Hz, 1H), 8.42 (d, J=9.0 Hz, 1H), 8.21 (s, 1H), 7.99 (t, J=1.6 Hz, 1H), 7.94 (d, J=8.0 Hz, 1H), 7.75-7.68 (m, 2H), 7.65 (s, 1H), 7.60 (d, J=7.3 Hz, 1H), 7.58-7.54 (m, 2H), 7.48 (t, J=7.6 Hz, 1H), 7.42 (t, J=7.9 Hz, 1H), 6.98 (d, J=2.6 Hz, 1H), 6.76 (d, J=8.8 Hz, 1H), 4.76 (d, J=5.9 Hz, 2H), 4.48 (s, 2H), 3.82-3.80 (m, 2H), 3.72-3.70 (m, 2H), 3.67-3.63 (m, 4H), 3.60 (s, 4H), 3.53-3.51 (m, 2H), 3.32 (quar, J=7.2 Hz, 4H), 2.90 (s, 1H), 1.13 (t, J=6.8 Hz, 6H). MS (ES, m/z): 777.4 [M+H]+.
