To a solution of N-({3-[(3-bromo-5-chlorophenyl)oxy]-4-chloro-2-fluorophenyl}methyl)-4-chloro-1H-imidazole-5-carboxamide (70 mg, 0.142 mmol), palladiumbisdichlorobistriphenylphosphine (9.96 mg, 0.014 mmol), copper(I) iodide (1.351 mg, 7.09 μmol) and TEA (0.099 ml, 0.710 mmol) in THF (6 ml) was added (2R)-3-butyn-2-ol (24.85 mg, 0.355 mmol) and the reaction mixture was irradiated in a personal microwave reaction for 10 minutes at 120° C. The reaction mixture was diluted with EtOAc and washed with water. The solvent was removed and the crude material was purified via reverse phase HPLC to give 4-chloro-N-{[4-chloro-3-({3-chloro-5-[(3R)-3-hydroxy-1-butyn-1-yl]phenyl}oxy)-2-fluorophenyl]methyl}-1H-imidazole-5-carboxamide (16 mg, 0.033 mmol, 23% yield). 1H NMR (400 MHz, METHANOL-d4) δ ppm 7.24-7.45 (m, 3H), 7.11 (s, 1H), 6.89 (s, 1H), 6.74 (s, 1H), 4.47-4.70 (m, 3H), 1.41 (d, 3H). LC-MS (ES+) m/z 482.03, [M+H].
