Reaction Steps

A mixture of 0.0098 mol of 4-(5-methoxycarbonylindol-3-yl)butyl methanesulfonate (preparation as described in Example 3) and 0.0097 mol of 4-(2-oxo-2H-1-benzopyran-6-yl)piperazine is heated in acetonitrile for about 96 hours on a steam bath. The reaction mixture is worked up in the customary manner and purified. Methyl 3-{4-[4-(2-oxo-2H-1-benzopyran-6-yl)-1-piperazinyl]-butyl}indole-5-carboxylate is thus obtained.
