反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: N,N-diethyl-5-bromo-2-furancarboxamide (1.5 g) was treated with 6-[(6-bromohexyl)oxy]-1-hexyne (1.59 g) and N,N-dicyclohexylamine (2.10 g) according to the method of Intermediate 9 except that the reaction mixture was refluxed under nitrogen for 3 h and FCC eluting with hexane followed by hexane:ether (4:1→1:1) gave the title compound as an orange oil (1.90 g), t.l.c. (hexane:ether 1:1) Rf 0.15. was refluxed under nitrogen for 3 h FCC eluting with hexane

实验步骤: 5-Bromo-N,N-diethyl-2-furancarboxamide (2.0 g) was treated with 3-[(6-bromohexyl)oxy]-1-propyne (1.87 g) according to the method of Intermediate 9 except that the reaction mixture was stirred under nitrogen at 60° for 4 h, and hexane-ether (5:1 then 2:1 then 1:1) was used as the eluant for FCC. This afforded the title compound as a dark yellow oil (2.98 g), t.l.c. (diethyl ether) Rf 0.35.
