Reaction Steps
To a solution of (2E)-3-{1-[bis(4-fluorophenyl)methyl]-3-cyano-4,6-dimethyl-1H-pyrrolo[2,3-b]pyridin-2-yl}prop-2-enoic acid (300 mg, 0.677 mmol) in THF (3 ml) were added DMF (0.03ml) and oxalylchloride (0.071 ml, 0.813 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 2,2-dimethyltetrahydro-2H-pyran-4-ylamine (175 mg, 1.35 mmol), triethylamine (0.313 ml, 2.25 mmol) and THF (2 ml), and the mixture was stirred under ice-cooling for 2 hours. The reaction solution was poured into water and extracted with ethyl acetate. The extract was washed with water and dried over anhydrous magnesium sulfate, and the solvent was distilled off under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=2:1) to give the objective product as a solid material.
