3-Bromoquinoline → 6-(Quinolin-3-yl)hex-5-yn-1-ol

Participants

Reaction Steps

6-(3-Quinolinyl)-5-hexyn-1-ol was prepared in the manner described above in Example 105 starting with 15.0 g of 3-bromoquinoline, 8.5 g of 5-hexyn-1-ol, 1.05 g of bis(triphenylphosphine)palladium dichloride and 0.10 g of cuprous iodide in 115 ml of dichloromethane and 28.5 ml of triethylamine. The crude product was chromatographed on a preparative high pressure liquid chromatograph eluting with 2.5% methanol-dichloromethane to give 14.4 g (89%) of 6-(3-quinolinyl)-5-hexyn-1-ol as a colorless oil. A portion was purified further on a silica thick layer plate eluting with 10% methanol-dichloromethane and solidified on drying, mp 47°-48° C.
