1H-Indole 3-acetic acid (1.05 g, Aldrich) and trans-N-methyl-2-(1-pyrrolidinyl)cyclohexanamine were dissolved in tetrahydrofuran (30 ml) and cyclohexyl carbodiimide (1.24 g) added. The resultant solution was stirred at room temperature overnight, during which time a white precipitate appeared. The solution was filtered and evaporated to an oil, which was chromatographed on silica. Elution with ether gave the product as a white solid (1.3 g), mp 175°-178° C.
