Procedure

0.088 g of N-[6-(1-benzyl-pyrrolidin-3-yl)-pyridin-3-yl]-4-isopropyl-benzene-sulfonamide (0.25 mmol) were dissolved in 10 ml of dichloromethane. 0.022 g of propionyl aldehyde (0.38 mmol), 0.023 g of acetic acid (0.38 mmol) and 0.081 g of sodium triacetoxyborohydride (0.38 mmol) were added and stirred for 1 h at room temperature. Water was added, the pH adjusted to 10 with 1 N sodium hydroxide, extracted three times with ethyl acetate, the organic layers combined and evaporated to dryness. The crude material was purified via silica gel chromatography with dichloromethane/methanol 20%. Fractions containing the product were combined and the solvent evaporated to yield 0.026 mg of the product.
