Versuchsvorschrift

Added 2-Fluoro-6-methoxy benzaldehyde (20 mg, 0.129 mmol) to a solution of (R)-5-(1-methyl-5-(piperidin-3-yl)-1H-1,2,4-triazol-3-yl)-3-(pyridin-4-yl)-1H-indazole (15 mg, 0.0379 mmol) and sodium triacetoxyborohydride (25 mg, 0.118 mmol) in MeOH (4 ml) at room temperature, then stirred for 2 hours. Reaction was diluted with CH2Cl2 (50 ml) and H2O (25 ml), organic layer was separated, dried over Na2SO4, filtered and solvent evaporated. The residue was chromatographed on silica gel eluting with 5% v/v MeOH/CH2Cl2/NH4OH to yield (R)-5-(5-(1-(2-fluoro-6-methoxybenzyl)piperidin-3-yl)-1-methyl-1H-1,2,4-triazol-3-yl)-3-(pyridin-4-yl)-1H-indazole as a white solid (12 mg).
