実験手順

A mixture of 9.28 g of 5-chloro-3-(1,2,3,6-tetrahydropyridin-4-yl)-1H-indole (prepared by the process of Belgium Pat. No. 858,101), 140 ml of dimethylformamide, 8.48 g of sodium carbonate and 4.67 g of propyl iodide was stirred for 5 hours at room temperature under an inert atmosphere and was then poured with stirring into 1.4 liters of water after which crystallization occured. The mixture was filtered and the recovered product was rinsed with water and dried under reduced pressure in the presence of a dehydrating agent. The product was crystallized from ethanol to obtain 6.95 g of 5-chloro-3-(1-propyl-1,2,3,6-tetrahydropyridin-4-yl)-1H-indole hydrochloride melting at 229°-230° C.
