For example, 9-(N-carbazolyl)-5, 7-nonadiyn -1-ol (5) is synthesized in about 80% yield by cross coupling of 3-(N-carbazolyl)-1-propyne (3) with 6-bromo-5-hexyn-1-ol (6), which, in turn, is synthesized from 5-hexyn-1-ol with sodium hypobromite. Reaction of (5) with methylisocyanate (7) gives 9-(N-carbazolyl)- 5,7-nonadiyn-1-ol methylurethane (8) in almost quantitative yield. ##STR12##
