実験手順
A mixture of a solution of 5 g of the product of Step D of Example 3 in 50 ml of dimethylformamide, 7 g of sodium carbonate and 2.3 ml of n-propyl iodide was stirred for 16 hours under an inert atmosphere and was then poured into 250 ml of iced water. The mixture was extracted with ethyl acetate and the organic phase was washed with aqueous saturated sodium chloride solution, dried and evaporated to dryness under reduced pressure. The residue was chromatographed over silica gel and was eluted with an 8-1-1 cyclohexane-chloroform-triethylamine mixture. The eluate was distilled to dryness under reduced pressure to obtain 4.84 g of 3-(3-methoxyphenyl)-1-propyl-1,2,5,6-tetrahydropyridine.
