実験手順: Sodium cyanoborohydride (6.4 g) was added in several portions to a solution of 6.0 g 2-(2-aminophenyl)-1H-indole in 200 ml HOAc at 5° C. The resulting solution was stirred at room temperature overnight. Water was added and the reaction mixture was concentrated. The residue was diluted with ice water and made basic with 50% NaOH. This mixture was extracted with Et2O and the extracts were washed with water and saturated NaCl solution, and dried (MgSO4). Concentration gave 6.1 g crude product which was chromatographed by HPLC to give 3.05 g solid, m.p. 115°-117° C. the reaction mixture was concentrated The residue was diluted with ice water This mixture was extracted with Et2O the extracts were washed with water and saturated NaCl solution dried (MgSO4) Concentration gave 6.1 g crude product which was chromatographed by HPLC

実験手順: To a mixture prepared from 7.6 g of 2-(2-aminophenyl)indole, 2.5 ml of acetic acid and 90 ml of ethanol was added 7.4 ml of 1-phenylmethyl-4-piperidone. The resultant solution was refluxed for 6 hours. Concentration gave a solid/gum mixture which was taken up in EtOH and treated with dilute NH4OH. Filtration gave 12.45 g of yellow solid. This was recrystallized from CH3OH/H2O to give 9.0 g of yellow solid. High vacuum drying (90°) gave 2.6 g of dark yellow solid, m.p. 155°-157° C. Concentration gave a solid/gum mixture which Filtration
