Potassium carbonate (0.5 g) was added to a solution of 1-(piperidin-4-yl)-6-acetamidomethylindole (0.10 g) obtained in Example 386-1) and 4-(1-hydroxyethyl)phenethyl bromide (0.07 g) obtained in Production Example 19 in N,N-dimethylformamide (5 ml) and the resultant mixture was stirred at 70° C. for 6 hr. Then the reaction mixtures were concentrated under reduced pressure and the residue was partitioned between chloroform (40 ml) and water (15 ml). The chloroform layer was washed with brine, dried over magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (chloroform/methanol system) to give the title compound (0.07 g) as a pale yellow wax (yield: 45.3%).
