A mixture of 2-bromoquinoline (3.00 g), 6-[(6-bromohexyl)oxy]-1-hexyne (3.77 g), BTPC (90 mg), copper (I) iodide (11 mg) and dicyclohexylamine (2.79 g) in acetonitrile (35 ml) was stirred at room temperature under nitrogen for 20 h. The mixture was diluted with ether (90 ml), filtered and the filtrate evaporated in vacuo to give a brown oil. Purification by FCC eluting with hexane:ether (4:1→2:1) gave the title compound as a brown oil (4.25 g), t.l.c. (hexane:ether 2:1) Rf 0.22.
