Versuchsvorschrift

1-[1-(4-Fluorophenethyl)piperidin-4-yl]-6-bromoindole (0.2 g) was dissolved in toluene (2.50 ml). Next, 1-methyl-2-tributylstannylpyrrole (1.44 g) synthesized in accordance with the method described in Tetrahedron Lett., 4407 (1986). with the use of 1-methylpyrrole and tributylthin chloride was added thereto and the resultant mixture was heated under reflux for 3 hr under nitrogen atmosphere. After adding ethyl acetate, the mixture was washed with brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane/ethyl acetate system) to give the title compound (0.115 g) as a yellow oil (yield: 57.28%).
