Versuchsvorschrift

To a solution of 1-(6-chloro-quinolin-8-yl)-piperidin-4-one (Step 1, 0.13 g) and of 4-piperazino-indole (commercially available, 0.100 g) in 15 mL CH2Cl2 in 10 mL of dichloroethane, was added 0.137 g of sodium triacetoxyborohydride and 0.1 mL acetic acid. The reaction was stirred at room temperature overnight. It was quenched with 1N NaOH, and the product was extracted with CH2Cl2. The organic phase was washed with water and dried over magnesium sulfate. The product was filtered through 100 ml of silica gel using 100% Ethyl acetate, to give 0.070 g of the desired product. Mp: 224° C.; MS (ES) m/z (relative intensity): 447 (M++−H, 100).
