Versuchsvorschrift

To a solution of 5-(5-formyl-3-thienyl)-3-{1-[(1-methylethyl)sulfonyl]-4-piperidinyl}-1H-indole-7-carboxamide (40 mg, 0.09 mmol) in DMSO (2 mL) was added [2-(ethylthio)ethyl]amine (105 mg, 1 mmol), acetic acid (50 μL), and sodium triacetoxyborohydride (212 mg, 1.0 mmol). The resulting mixture was stirred overnight. To the mixture was added sodium cyanoborohydride (80 mg, 1.2 mmol) and stirred overnight followed by addition of formaldehyde (100 μL, 1.2 mmol). The mixture was then stirred for an additional 3 h. It was then purified by Gilson Preparatory HPLC to give 7.0 mg of the title compound.
