Versuchsvorschrift

A mixture of 4-(1H-pyrazol-4-yl)-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrolo[2,3-b]pyridine (0.811 g, 2.58 mmol), 4-[3-(cyanomethylene)azetidin-1-yl]-N-isopropylbenzamide (0.625 g, 2.45 mmol) and 1,8-diazabicyclo[5.4.0]undec-7-ene (190 μL, 1.3 mmol) in acetonitrile (8 mL, 200 mmol) was heated at 50° C. for 1 hour. After cooling, the solvent was removed under reduced pressure. The residue was diluted with dichloromethylene, neutralized with 0.5 N HCl aqueous solution to about pH 7. The organic layer was washed with brine, dried over MgSO4, filtered and concentrated under reduced pressure to afford the desired product (1.40 g, 84.3%), which was directly used in the next step reaction without further purification. LCMS (M+H)+: m/z=570.3.
