Procedure
The starting product was prepared according to the same procedure as that described in the last paragraph of Example 2. 9.5 g of 5-fluoro-indole (U.S. Pat. No. 879,619) and 11 g 4-vinyl-pyridine were refluxed for 6 hours in 50 ml acetic acid. The mixture was then poured onto 300 g of crushed ice and alkalinized with a 20% potassium carbonate solution. A precipitate formed which was squeezed and washed in water several times. After drying under vacuum, 12 g of 3-[2-(4-pyridyl)-ethyl]-5-fluoro-indole were obtained which melted at 128° C.
