Example 71 (2E)-3-(1-benzhydryl-3-cyano-4,6-dimethyl-1H-pyrrolo[2,3-b]pyridin-2-yl)-N-tetrahydro-2H-pyran-4-ylprop-2-enamide To a solution of (2E)-3-(1-benzhydryl-3-cyano-4,6-dimethyl-1H-pyrrolo[2,3-b]pyridin-2-yl)propenoate (300 mg, 0.759 mmol) in THF (3 ml) were added DMF (0.03 ml) and oxalylchloride (0.0796 ml, 0.912 mmol), the mixture was stirred at room temperature for 1 hour, and the solvent was distilled off under reduced pressure. The residue was added under ice-cooling to a solution of tetrahydro-2H-pyran-4-ylamine hydrochloride (184 mg, 1.51 mmol), triethylamine (0.560 ml, 4.01 mmol) and THF (3 ml), the mixture was stirred under ice-cooling for 1 hour and at room temperature for 12 hours. The reaction solution was poured into water, and extracted with ethyl acetate. The extract was washed with water, dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure. The residue was recrystallized from hexane and ethyl acetate. Yield (amount) 173 mg, yield (rate) 46.5percent 1H-NMR (CDCl3) delta: 1.26-1.62 (2H, m), 1.84-1.90 (2H, m), 2.57 (3H, s), 2.75 (3H, s), 3.38-3.49 (2H, m), 3.92-4.10 (3H, m), 5.54 (1H, d, J = 8.2 Hz), 6.78 (1H, d, J = 15.8 Hz), 6.92 (1H, s), 7.20-7.45 (11H, m), 8.05 (1H, s). IR (KBr) cm-1; 3300, 2215, 1657, 1618, 1591, 1547, 1426, 1335, 912, 735, 698.
