Participants

Reaction Conditions

Reaction Steps

A mixture of 1-methyl-2-iodoindole (4.40 g, 17.3 mmole), sodium trifluoroacetate (24.0 g, 176.5 mmole) and copper(I) iodide (17.1 g, 89.8 mmole) in N-methylpyrrolidone is heated at 160° C. for 6 hours, cooled to room temperature, diluted with water and filtered through diatomaceous earth to remove copper salts. The filtrate is extracted with ether. The extracts are combined, washed with water, dried over MgSO4 and concentrated in vacuo to give a residue. The residue is chromatographed using silica gel and 4:1 hexanes:ethyl acetate as eluent to give the title product as a pale yellow oil which crystallized on standing, 119 g (37% yield), mp 28°-32° C., identified by IR, 1HNMR and 19FNMR analyses.
