Procedure
A solution of 9.3 g of the free base of Example 10, 300 ml of lN hydrochloric acid and 100 ml of ethanol was refluxed for 3 hours and the mixture was diluted with water and made alkaline. The aqueous phase was saturated with potassium carbonate and was extracted with ethyl acetate. The organic phase was chromatographed over silica gel and eluted with a 6-3-1 cyclohexane-chloroform-triethylamine mixture to obtain 7.7 g of 4-(1H-indole-4-yl)-α-[[2-(2-propenyloxy)-phenoxy]-methyl]-1,2,3,6-tetrahydro-1-pyridine ethanol with an Rf=0.05.
