実験手順
A mixture of 10 g of 3-(1H-indol-4-yl)-3-piperidinol hydrochloride in 200 ml of dimethylformamide was agitated for 4 hours under an inert atmosphere with 13.44 g of sodium carbonate and 4.2 ml of ethyl bromide. The mixture was taken up in water and was extracted with ethyl acetate. The organic phase was washed with water, dried, filtered and evaporated to dryness under reduced pressure at 50° C. The residue was purified by chromatography over silica and eluted with a 6-3-1 mixture of cyclohexane-chloroform-triethylamine to obtain 6.6 g of 1-ethyl-3-(1H-indol-4-yl)-3-piperidinol which was used as is for the following step.
