Reaction Steps

4-bromobenzonitrile (182 mg, 1 mmol), phenylpent-1-en-4-yn-3-ol (190 mg, 1.2 mmol), bis(triphenylphosphine)palladium(II)dichloride (14 mg, 0.02 mmol), copper iodide (3 mg, 0.03 mmol) and triphenylphosphine (52 mg, 0.2 mmol) were introduced in a 10 mL microwave vial flushed with argon. This was diluted with anhydrous triethylamine (700 μL, 4 mmol) in anhydrous degased 1,4-dioxane (1.3 mL). The solution was heated under microwave irradiation at 120° C. for 45 min. The reaction mixture was poured into a mix of 1M aqueous solution of hydrochloric acid (10 mL) and saturated aqueous ammonium chloride solution (10 mL), and this was extracted with ethyl acetate (3×15 mL). The combined organic layers were dried over magnesium sulfate, filtered, and evaporated to dryness to give crude product which was purified by flash chromatography (SiO2, 30% ethyl acetate in dichloromethane). This gave pure final compound TG007A82 (160 mg, 62%) as a light yellow powder.
