Reaction Steps

13 g (0.1 mol) of 5-methylindole are added to 4 ml of trimethylbenzylammonium hydroxide and 10 ml of acrylonitrile in 100 ml of dioxane while stirring. The mixture is then heated at 80° C. for 2 h and subsequently left to stand at room temperature for 3 days. Very dilute acetic acid is then added in order to neutralize the base. Extraction with EA (3×30 ml) is then carried out. The combined organic phases are dried with Na2SO4 and concentrated in vacuo. The residue was chromatographed on SiO2 with DIP as eluent. Rf [DIP]=0.3.
