Steps:
General Procedure for the Palladium-Catalyzed Formation of Compounds 1:
General procedure: 2-methyl-4-phenylbut-3-yn-2-ol (1a): Into a dry Et3N solution (5 ml) containing iodobenzene (5.0 mmol), 2-methylbut-3-yn-2-ol (6.0 mmol) and triphenylphosphine (4 mol %), CuI (5 mol %) was added and the reaction mixture was stirred for 2 min. After the solution was purged with nitrogen for half an hour, PdCl2(PPh3)2 (0.5 mol %) was added and the flask was flushed with N2, sealed and allowed to stir at 50°C for 4 h. The resulting reaction mixture was concentrated under vacuum The residue was purified through column chromatography (silica gel, hexane/ethyl acetate as eluent) to afford a yellow oil.
