Reaction Steps

2.5 g of 2-(4-bromobutoxy)-N-(1H-indol-4-yl)benzamide of Example 33, 2.71 g of 1-[2-(3,4,5-trimethoxyphenyl)ethyl]piperazine [German Patent No. 3,347,173] and 0.683 g of sodium carbonate in 25 ml of ethanol were heated to 60° C. for 10 hours and the mixture is cooled and poured into water and extracted with ethyl acetate. The extract was washed with water and dried and the solvents were evaporated under reduced pressure. The residue was chromatographed over silica (eluant: chloroform/acetone/triethylamine 6:3:1) to obtain 3.51 g of N-(1H-indol-4-yl)-2-[4-[4-[2-(3,4,5-trimethoxyphenyl)ethyl]-1-piperazinyl]butoxy]benzamide.
