Reaction Steps

To a solution of N-{-4-[5-bromo-4-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-1,2,4-triazol-3-yl)-2-furyl]-5-methylpyridin-2-yl}acetamide (0.19 g, 0.38 mmol) in DMSO (3 mL) was added N,N-dimethylpiperidin-3-amine (0.25 g, 1.9 mmol). The mixture was allowed to stir at 120° C. for 48 h. The reaction mixture was diluted with EtOAc and washed with water. The organic solution was separated, dried over MgSO4, filtered and concentrated. The residue was purified by column chromatography to give N-(4-{5-[3-(dimethylamino)piperidin-1-yl]-4-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-1,2,4-triazol-3-yl)-2-furyl}-5-methylpyridin-2-yl)acetamide (0.15 g, 72%). LCMS (FA): m/z=540.7 (M+H).
