In each case 5-methoxy-3-piperidine-4-yl-1H-indole (169.3 mg, 0.735 mmole) in dioxane (4.5 ml) and the diastereoisomer mixture of (4-dimethylamino-4-phenylcyclohexylmethyl)-carbamic acid phenyl ester (259.0 mg, 0.735 mmole) were dissolved in two microwave reaction vessels. The reaction mixture was treated with microwave radiation as follows: experiment 1 (150° C., 52 minutes) and experiment 2 (200° C., 2 minutes). In each experiment the reaction mixture was worked up by distilling off the solvent in vacuo. The respective residue contained, apart from phenol, also the two diastereomers of 4-(5-methoxy-1H-indol-3-yl)piperidine-1-carboxylic acid-(4-dimethylamino-4-phenylcyclohexylmethyl)-amide. The diastereoisomers were separated and purified by flash chromatography on silica gel (30 g and 40 g). Methanol/EE (1:1, ca. 600 ml) was used as eluent. The non-polar diastereoisomer of 4-(5-methoxy-1H-indol-3-yl)piperidine-1-carboxylic acid-(4-dimethylamino-4-phenylcyclohexylmethyl)-amide [experiment 1 (116 mg, m.p. 106°-107° C., 32%) and experiment 2 (89 mg, m.p. 110°-112° C., 25%)], and the polar diastereoisomer of 4-(5-methoxy-1H-indol-3-yl)piperidine-1-carboxylic acid-(4-dimethylamino-4-phenylcyclohexylmethyl)-amide [experiment 1 (108 mg, m.p. 98°-100° C., 30%) and experiment 2 (92 mg, m.p. 92°-97° C., 26%)] were thereby obtained in pure form.
