    • note
    • We found that 2-ethanolamine and several water-soluble amines of high boiling points were effective for the coupling reaction of terminal alkynes with aryl bromide that had to be carried out at 60°C instead of aqueous ammonia. These findings will be reported in due course.

    • For example, the reaction of 5bb with n-heptyl iodide in the presence of KOH in DMSO afforded the corresponding ether in 98% yield.
