Versuchsvorschrift

2-(4-methoxy-7-(3-methyl-1H-1,2,4-triazol-1-yl)-1H-pyrrolo[2,3-c]pyridin-3-yl)-2-oxoacetic acid (1.5 g), 2-(piperidin-4-ylidene)-2-(pyridin-2-yl)acetonitrile hydrochloride (1.5 g), 3-(diethoxyphosphoryloxy)-1,2,3-benzotriazin-4(3H)-one (DEPBT) (2.1 g) and Hunig's Base (2 ml) were combined in 20 ml of DMF. The mixture was stirred at room temperature for 16 hours. DMF was removed via evaporation at reduced pressure and the residue was partitioned with MeOH (80 ml). The precipitate was collected via filtration to provide 0.85 g of the product, 2-(1-(2-(4-methoxy-7-(3-methyl-1H-1,2,4-triazol-1-yl)-1H-pynolo[2,3-c]pyridin-3-yl)-2-oxoacetyl)piperidin-4-ylidene)-2-(pyridin-2-yl)acetonitrile (IVe). 1H NMR (500 MHz, DMSO-d6) δ12.42 (s, 1H), 9.23 (m, 1H), 8.69 (m, 1H), 8.27 (m, 1H), 7.89 (m, 2H), 7.58 (m, 1H), 7.52 (m, 1H), 3.98 (s, 3H), 3.99-2.70 (m, 8H), 2.60 (m, 3H). MS m/z: (M+H)+ calcd for C25H23N8O3 483.19, found 483.18.
