Participants

Reaction Steps

In an inert atmosphere. 0.068 g of bis(triphenylphosphine)palladium dichloride and 0.013 g of cuprous iodide was added with stirring to a deoxygenated solution of 1 g of 8-bromoisoquinoline, 0.56 mL of propargyl alcohol and 2 mL of triethylamine in 25 mL of dichloromethane. The mixture was stirred at room temperature for 2 hours and then at reflux for 20 hours. The cooled reaction was filtered and the filtrate was concentrated in vacuo. The residual oil was purified by HPLC (ethyl acetate-toluene; 2:3) to yield 0.4 g of -(8-isoquinolinyl)-2-propyne-1-ol, mp 138°-139° C.
